We're supportive of this proposal and have begun prototyping it out (https://bugzilla.mozilla.org/show_bug.cgi?id=1850627).

It should address a major paint point for developers porting existing applications that assume synchronous I/O to the web (which uses promises). It's also a first step to supporting more powerful stack-switching features that could be useful to languages like Go/Dart/Kotlin.
