Whether to use an async stack or not is very application dependent. For something closer to an application server than a proxy server I’m unconvinced async would be superior to threads.
I feel that Rust should be competing with C/C++ here though. I want a modern language with the same speed and control of memory usage. What’s A little frustrating (and don’t get me wrong, I’m rooting for Rust to get there) is that it feels like it should be possible to offer this, at least for threaded web servers.
There are other interesting languages in this space that I really enjoy playing with. Both Nim and Zig generate native code and are really fun, albeit very different, languages to work with.
