Great to see this--there are some nice features that encourage using standard web technologies like forms, and some solid quality of life improvements.
However, I'm disappointed (but not surprised, this was listed as out of scope for 19) that triggering Suspense is still basically "use a framework that supports it." I have not been able to find any documentation or blog posts about the mechanism. I've tried to figure out how it works by looking at TanStack Query, but I've had limited success so far. I've found they're copying React's twist on Promises [1], but I haven't gotten this to work yet.
I know the general idea is you throw Promises, but Suspense explicitly forbids using promises created during rendering. This means you can't just interrupt the component's initial render to load some data, and then restart it when its data is avail

able. This means the component needs to deal with null data somehow, instead of, e.g., being able to call a custom `useSomeData` hook and rely on it to first suspend and then return the loaded data. Not having to deal directly with loading states in individual components could simplify things quite a bit.
Has anyone explored this side of Suspense?
