Async await isn't useful because it's more ergonomic. It's useful because it's low overhead. If you don't care about that then rust might not be the right language for you the same way a language with a GC might be better suited for most folks. For my domain, any other choice would have made rust untenable. Rust has made all the right choices that make it an excellent choice for code I was otherwise forced to use c or c++ for. Not every language must bend its ways for every possible user, and most folks get upset when that inevitable happens because it dilutes the qualities that made the language useful for the original set of folks it was primarily useful for. Being popular unfortunately comes with the curse of not pleasing everyone.
