Regex issues aren't at all overblown, at least in the fields I have worked in or in fields of people I have talked to. As for async in Rust, I wrote in another comment that yes that is an issue. What we need is std to define traits that all the different runtimes can implement. Because there are absolutely reasons to use alternative runtimes, depending on what you do. I mostly use embassy (embedded microcontroller development) for example. And if you want thread-per-core with io-uring you want glommio or monio. Smol is simple and compact. I could also see uses for async in desktop GUI or gamedev (but to my knowledge there isn't any runtime suitable for those domains yet).
