Agree. There's stuff missing, and there are problems which likely are "multiple Phd theses" level to solve cohesively. Either in Rust or a successor language when the problem space has been explored.

For me the most annoying part are the footguns async Rust introduces, which Rust generally is blessedly empty of compared to e.g. Go or other languages.

Like for example, cancellation safety, dealing with "long running" futures, cleanly terminating a program, deadlocks at a distance [1] and others I'm forgetting now.
