> this is how Windows NT has had async IO
Pretty much what I was thinking of. My understanding from reading some commentary in this area is the Linux implementation is yet a little botched due to how it handles waiting threads.

ASync I/O isn't limited to just storage, though. It's /all/ I/O.
And yes, the layered storage stack does have a performance penalty to it. But it's also infinitely more flexible, if that is what you need. Linux still lacks IOCP (which io_uring is not a replacement for).
Windows' VMM and OOM is also generally much better.
Theoretical or aesthetic advantages are no guarantee that the software in question will actually be superior in practice.
