Python venv is language specific, doesn't handle the interpreter version and doesn't handle C libraries.

I really don't understand why people do this: I get having a distaste for containers but some people, seeing the massive success of OCI images, mainly seem content on trying to figure out how to discredit its popularity, rather than trying to understand why it's popular. The former may be good for contrarian Internet forums, but the latter is more practically useful and interesting.

I say this with some level of understanding as I also have a distaste for containers and Docker is not my preferred way to do "hermetic" or "reproducible" (I am a huge Nix proponent.) I want to get past the "actually it was clearly useless from the start" because it wasn't...
