The Debian example you're referring to was back from the release of 11. It's rustc was only 3 months old and already couldn't compile. That's not a "Debian is old" problem and it was only one instance. I've run into the same problem on other OSes as well. No OS hosted repo can keep up with rust and it's particular selection of bleeding edge types.

And it's hardly every Rust thread. There are far too many rust threads to even count, let alone comment on.
