As for the rest of your points - I don't think they're applicable as well. I've found Rust to be super solid and the ecosystem a pleasure to work with. Could you give examples to support your claim?
Furthermore, all other criticisms you've mentioned specifically towards rust and the community of rust are literal opposites of everything I've experienced.
The community is friendly and helpful. Rust is extremely stable, both as code, and as far as the developers making sure to not break backwards compatibility, going as far as testing EVERY PROJECT available in crates.io for regressions. They are also extremely organized, having all discussions in well thought out and documented RFCs,and allowing all to give input on it all.
I don't know what problems you have with Rust. I'm sure there valid things to critize. But everything you mentioned is categorically false. If you disagree, I'd be open to see proof of it all.
The Rust community reminds me of how welcoming the Go community used to be... (I love Go and write it every day, this isn't some sort of commentary about Go).
