They are genuine issues, within Rust, but the way you /categorize/ the severity of the issue is different within language communities. They don't impact usability /much/ because of Rust's community, focus, size and niche.

Compile times in Rust are a problem, but the RLS does a good enough job of feedback and the development loop happens enough in compile time, that users don't miss it enough, compared to, say, Java which relies heavily on runtime behaviour/reflection for application behaviour.

Debugging token macros could be better, such as with a better macro-stepper, but you don't write enough macros in Rust to care heavily about it to make it a big deal, unlike in a Lisp.

Hot reloading would be nice, but not and ~essential~ part of development and deployment like in BEAM. Better reflection utilities might be nice but I doubt Rust libraries will ever be heavily dependent on it in the same way that Go or Java are.
