tions, and skepticism are very welcome. Thanks for reading. [1] https://github.com/mui/material-ui/issues/45759#issuecomment...

.com/mui/material-ui/blob/next/packages/mui-ma... or https://github.com/mui/material-ui/blob/next/packages/mui-ba...), but we still add our own automated and manual tests in our own usages. But then again I'm bad at math and division, lol, so maybe it's just my own weakness.

6115 - We have introduced styling props, and a sx prop: https://mui.com/system/basics/ - We have a growing set of alpha unstyled components, e.g. https://mui.com/components/autocomplete/#useautocomplete - We have incorporated a company, sustaining over 10 people. - We have introduced an advanced data grid: https://mui.com/components/data-grid/demo/ Thanks!

For dependencies that never make breaking changes you will be OK. But if the dependencies you have are likely to change and likely to be upgraded elsewhere in the codebase and potentially might make breaking changes, we should consider them a risk to the project. I agree that this should be highlighted -- but, in the context of what you were talking about, which was with regards to code that uses old features of React, you are incorrect. As I mentioned to you, compatibility packages exist for all old React lifecycle methods and deprecated patterns. Therefore, by design, you are not being forced to upgrade the patterns in old parts of your codebase. I am trying to make specific claims about concrete things that I can evidence. The existence of compatability packages for features that have been deprecated for 5 years invalidates a specific argument about needing to upgrade old React code due to changes in the API. > You've made several claims like that, > but in the absence of data there's no > way to know whether you're correct. > For example, preset-env has been in > production for 3+ years now and had > an extended beta/RC phase before that. > It's true that it defaults to ES5 if > you don't configure it, but the Babel > docs explicitly recommend that you do. > [..] > But it will take more than an unsupported > assertion to convince me that this has > been the norm for most web development > for quite some time. If it defaults to ES5 why are you asking for me to provide evidence as to whether companies have generally targetted IE11? It is the default; it is very unlikely that there is a majority of people that are configuring it... > But it will take more than an unsupported > assertion to convince me that this has > been the norm for most web development > for quite some time. My claims are the following: 1. ES5 has been the default for front-end packages published to NPM since it was released (https://twitter.com/_developit/status/1289317757146693632). (I'm linking to Jason Miller's tweets since he has been the one most obssessively pushing for this to change. The problem we've all been having is that the `package.json` fields do not make it explicit what syntax a package is using.) 2. IE11 is in rapid decline (https://twitter.com/TheRealNooshu/status/1348955568459968515) and only recently have big corporations dropped support for it (Atlassian (March 2020): https://blog.developer.atlassian.com/retiring-ie11-support-f... ; Microsoft 365 (August 2021): https://docs.microsoft.com/en-us/lifecycle/announcements/m36... ; LinkedIn, Twitter, etc (2020): https://twitter.com/swyx/status/1260627626739130369). As I said "most only dropped IE11 this year". I guess I was off by one year, but I was talking about recent announcements. For context, this was to evidence my opinion that the JavaScript community has been very slow moving and careful to output code that is executable by old browsers to the extent that we've supported a browser released in 2013 and used a syntax released in 2009. > And these kinds of things are advanced > tooling, in your view? Check back to my text and you will see that I made no such claim. You claimed that "the language doesn't provide much to help with building large-scale software and maintaining it over the long term" so I demonstrated that we have all of the necessary tooling to do so and invalidated this. > We had those in our IDEs for building > desktop software back in the last > century. Except they were automating > rewriting millions of lines of code [...] Can you point me towards examples of the usage of AST rewriting tools that are actively being used by open-source library maintainers in other ecosystems to help their consumers do upgrades in large code-bases (e.g. I can see that `clang` has AST tooling, but I don't see examples online of this being widely used: https://devblogs.microsoft.com/cppblog/exploring-clang-tooli...). Within the JavaScript ecosystem this is quite popular (1. https://github.com/reactjs/react-codemod ; 2. https://github.com/mui-org/material-ui/tree/HEAD/packages/ma... ; 3. https://github.com/emotion-js/emotion/tree/main/packages/esl... ; etc.) Teams that maintain huge codebases have tooling to safely automate their upgrades and the best library maintainers provide their consumers with these AST transformations. > Don't tell that to anyone who uses > React Router.

I agree that those particular libraries haven't been maintained well (they make extraordinarily large changes in major versions to the extent that sometimes it might as well be a whole new library). > I encourage you to look at what is considered the norm > and acceptable practice in fields where better quality > and greater longevity are more highly valued.

I think your argument has been a moving target. Originally, you pointed your finger at React saying it has a stability problem, so we showed you that they've been incredibly good at keeping backwards compatibility and that you could upgrade your version of React to regain access to the ecosystem's newest libraries built on top of new APIs without needing to rewrite your legacy code through the usage of compatability packages. Then you implied that it was an overall JavaScript ecosystem stability problem, so I showed you the level of effort that TC39 and the brower maintainers go to keep backwards compatability. And I showed you that most in our ecosystem have been carefully supporting the lowest commmon demominator users for almost a decade by producing web apps that work in IE 11 and packages that first-class ES5 syntax, and gave you examples of big webapps that only recently broke from this tradition. Now you are pointing at exceptional cases involving particular poorly maintained libraries and tools, and telling me that we lack tooling to deal with scale (which is a separate concern). If you don't think Webpack and React Router are good citizens with regard to their API stability and this annoys you because you like to be on the latest/greatest then don't use them. I and many others also specifically avoid these libraries/tools and yet don't paint the whole ecosystem with this one brush. (On the topic of tooling, it has only been very recently that we've been getting tooling that can deal with high-scale development, however it is happening now.) * * * I think that possibly what you're noticing is the second-order effect of more and more usages of JavaScript and web technologies causing new APIs to steadily be added to the web with the old APIs remaining forevermore. The original APIs were made to display and navigate documents. As the years have passed more and more APIs have been released to support more complex types of applications and this resulted in overall churn in user-space as library creators iterate to produce better domain-specific APIs. We provide a high-level of user-facing stability despite this. I don't think it is fair to compare what we are trying to achieve to what is important when controlling industrial machinery. The use cases of that are much more static, while in 2021 people on the Web are creating tools like Figma (https://www.figma.com/), Office 365 (https://www.office.com/), Buerli (https://buerli.io/), and Spline (https://spline.design/). This is very far diverged from where we started and the fact it has been achieved without breaking the web is impressive. It's also quite clear to me that high-quality tools like these aren't achievable without the creation of impressive and scalable tooling (some of which has been released to the public). OK, let's agree to disagree...
