Good point, but the devil lies in the details. How should the timers behave? Is the clock monotonic? Are tasks spawned on the same thread? Different platforms and executors have different opinions. Maybe it's still possible and just a lot of work?

Yeah, I think that's the current status. I believe it was for a long time (and possibly still is) blocked on language improvements to async traits (which didn't exist at all until relatively recently and still don't support dyn trait).

This is true, but perhaps not uniquely so, when compared to platform dependence of the standard libary already. File semantics, sync primitive gaurantees and implementations, timers and timer resolutions, etc have subtle differences between platforms that the Rust stdlib makes no further gaurantees about.
