Specifically the case of request management, it's already implemented and available in all browsers practically. It's like four lines of code you have to add/change, to be able to cancel a request. https://developer.mozilla.org/en-US/docs/Web/API/AbortContro...

Regarding other cases, there are already ways of handling those. I don't think just because many ask about something, doesn't mean it's not currently working.

There are a lot of issues with the ergonomics of AbortController. It's very low level.

Did you actually look at the link I sent you? It's absolutely not low level. If you know how to use window.fetch, you know how to use AbortController already.

   controller = new AbortController();
   const signal = controller.signal;
   fetch("http://example.com", { signal: signal })
   // abort request
   controller.abort();

It basically couldn't be simpler? What sort of API would you like to be able to cancel requests?

That's a toy example! In reality in a complex app you'd usually be aborting far from where the fetch is created, and you'd have large promise chains where the semantics of cancellation are non-obvious and even unintuitive.
