I mostly agree with your sentiment, but at the same time I remember being quite skeptical of the possibility of Rust getting async/await at all because I saw no way around the lack of immovable types in the language, and I thought it would be way to disruptive to add it. And then Pin came and allowed to work around that issue (don't get me wrong, Pin is a dirty hack and I hate it, but at least it works, even if it makes tge ergonomics questionable for some use-cases…).

Since then reserve my judgment on stuff I think to be impossible.

Yeah, like I said it’s a trickle at this point.

You're misunderstanding the problem entirely. Even if you could implement it overnight, it would be unlikely to ship.
