Do you mean cancellable promises were cancelled, or AbortSignal was cancelled? Because they went with the latter in the end. It got a bit fuzzy for a couple of years tbh. Personally I wanted cancellable promises because reasons, but i can appreciate the DRY aspects of AbortController and stuff going on in other APIs.
As recently as September the AbortSignal approach was implemented in Edge 16 and Firefox 57!

I don't think you can cancel a fetch - cancelling Promises was abandoned.
