> The problem is that the entire ecosystem has completely shifted to async. There are almost no active / popular libraries related to network IO The ecosystem, or the ecosystem where network IO is a thing? Surely that's just a corner of the Rust library ecosystem. I have almost never used network IO (databases, http,...) in 20 years of programming, and zero times in Rust. There is a big (and might I say extremely comfortable) world of programming everything is on one machine, and things are CPU instead of IO bound.
