I think Debian's system should have a system only environment with their pre-frozen packages, and then a userland specific environment, where you can install any version of anything, and none of the system packages are affected by these software packages, but when you open a terminal for dev work, you can choose a more modern Python, or what have you. I'm seeing an uptick in what they call "atomic" systems, where this is exactly the case, but last I tried to install one, it didnt even register correctly on boot up, so until I find one that boots up at all, I'll be on POP OS.
