I don't get it... Can't you just use a virtualenv? Then there's no worry about namespace pollution or conflicts between dependencies of different projects.
This is becoming a parody of software engineering. People are now irrationally scared of using dynamic libraries, OS packages and even directories, like virtualenvs. Instead, a simple solution is replaced with containers, or by rewriting tons of code in the new hyped language. Are we trying to create job security through unnecessary complexity?
As a python/go dev, I can assure you that go is not much more complex. And as a server admin, it's much easier to deploy.
It does have drawbacks when compared to python, but it can often be the optimal solution.
