rustup still is outside of repos even if the download method isn't silly and insecure. For some random applications that's fine, but for a compiler and toolchain? No. If I wanted a rolling distro I'd use a rolling distro. Rust culture only being compatible with rolling is not a good thing for many use cases.
>Which languages do you use?
c, c++, perl, bash. A program written in perl+inline c today will compile and run on system perl+gcc from 2005. And a perl+inline c program written in 2005 will compile and run just fine on system perl+distro today. And pure Perl is completely time/version portable from the late 90s to now and back. No need for containerization or application specific installs of a language at all. System perl just works everywhere, every time.
There are versions of c++xx isms and non-c89/etc isms in some programs written in these languages. But at least these only happen a couple times a decade and because of the wide popularity and dev culture their use is much more delayed after introduction than in rust or python.
