Sure, but that’s not really an argument for or against async but for or against different runtime policies.

What good are "runtime policies" if you're in a single thread that you can't interrupt (which is what async is)?
Async is not really that in Rust. While it's true that a singular poll cannot be preempted, things like task::spawn schedule that on a multi threaded executor. So a lot of cases behave just like threads except you await them from somewhere else.
