or find ways to override and install latest, for example latest LLVM that would work on debian stable - https://apt.llvm.org/ (maybe similar for rust?). I've switched to this on my debian stable so that I can compile carbonlang (it needs llvm12, debian stable had only llvm11) - with above I've actually got llvm15, and then week ago switched to llvm16 (I can adjust that back to say llvm14 if I want).
