I mean, like I said, there's really just venv and pip, and mentally I almost consider them the same tool (some say they ought to have been).

Node avoids the need for a "venv" because each project has its own "venv", which if you have a 700mb pytorch install, ick.

Rust/go don't deal with .so files to the extent python does, so cargo/godep have an easier time. Python is a C abstraction layer.

So like, I'm not sure how much less you need than "package manager" and "env manager".
