From the project README

An excerpt from the repository, fetched Nov 13, 2026.

Read the project’s introduction
Web Components Web Components are a new browser feature that provides a standard component model for the Web, consisting of several pieces maintained in different places: Shadow DOM Most of the parts are now maintained in DOM Standard, called shadow trees. Some of the parts are still remained in this repository. See Issue #661 for the progress of upstreaming those parts from the partially out-of-date Shadow DOM document. Issues against the DOM and HTML Standard. Issues raised in this repository. The old issue tracker on W3C bugzilla, which is no longer used. Custom Elements Custom elements were upstreamed into the HTML Standard (and bits in the DOM Standard) and are maintained there. Issues against the DOM and HTML Standard. Issues raised in this repository. The old issue tracker on W3C bugzilla, which is no longer used. HTML Templates HTML Templates were upstreamed into the HTML Standard and are fully maintained there. CSS changes The CSS WG works on CSS Scoping and CSS Shadow Parts, which help dealing with shadow trees with various selectors. Various other parts of CSS and its object model are also impacted by shadow trees and directly worked on in the various CSS specificaions. Issues against the CSS WG repository. JSON, CSS, HTML Modules Successor to the abandoned HTML Imports, allows JSON, CSS, and HTML markup to be requested by a component. HTML Modules Spec work is being incubated upstream in whatwg/html (see PR). For new issues, please file against whatwg/html or here in w3c/webcomponents. See also the HTML Modules explainer, initial proposal, and earlier design ideas. Issues raised in HTML Standard Issues raised in this repository. Includes related issues for other potential module-types, such as CSS and JSON. Old issue tracker includes a few issues filed when the feature was first proposed. Please avoid filing new issues there. Issues Please file issues in the most specific repository possible, per the above issue pointers. (It's often not this repository.) Abandoned features: HTML Imports The current issue tracker. The old issue tracker on W3C bugzilla, which is no longer used. Note: HTML Modules are intended to replace HTML Imports (see above).

Support for anything web components-related is a death by a thousand cuts both for the browsers and for the framework authors. For the browsers: Shadow dom breaks almost literally everything. It's a parallel world that exists on its own and that needs dozens of additional web standards to patch holes introduced by it. And delays dozens of useful web standards that now have to be aware of it. On top of that nothing in web components is ever created thinking even one step ahead, and break multiple pieces of basic functionality. It's a collection of barely fitting patches. E.g. at first they couldn't send data in forms. Enter FormData. Oops, still cannot be a custom form submit button. Here's a 7-year old still unresolved issue: https://github.com/WICG/webcomponents/issues/814 For frameworks: Framework authors have to patch all thise holes o

n their own. Because unlike web components they actually do care about standards and browser functionality. If styles don't work, forms din't work, code doesn't work etc. because of web components, it's the framework that will be blamed. It doesn't help that there's an insane amount of work involved in figuring out all the ways they are broken. See for example: https://xcancel.com/Rich_Harris/status/1841467510194843982#m
In Progressive Web Components
The only browser Apple is blocking it on is Safari: other browsers implement it just fine, and the standard passed over Apple's objections. The rationale was architectural, arguing that extending built-in components would lead either to brittle components that would break when new properties were added or causing the specification of builtin components to freeze forever to avoid such breakage. I'm not sure I buy the arguments 100%, but for sure it's not evil/incompetent board executives twirling their mustaches as they deliberately break the web: https://github.com/WICG/webcomponents/issues/509#issuecommen...
