The #TypeScript compiler might not be the fastest - but why is that such a big problem?
"We have a large project" - I get that, but there are other things you can do that will impact development speed and DX: 1) decouple type checking from development

Coupling your dev server start & reload with type-checking is not only slow and mostly unnecessary, it's also hindering. Comment out one line of code, see an error in the browser because of unnecessary import... why?

So the `use` proposal is quite interesting, there's some chatter already about it being an out-of-the-box react-query together with the yet unknown cache api.

Let me elaborate why I do not think that's the case. The reports of react-query's death are greatly exaggerated: The obvious one is: react-query does so much more. It tries to keep your application in-sync with your server state.

Smart refetches; interval refetching; retries; infinite queries; offline support; lagged data; persisters; prefetching; hydration for SSR;
