I also wondered the same thing, but the issue seems to be mostly for people who want to distribute tools built in Python via Linux package managers
i.e. it should be possible to do that and not have to explain to users that it even uses Python, and certainly not that you have to first set up a virtualenv, then pip install dependencies etc
It's a use case I've never had, and mostly just accepted that Python was ill-suited for, but I can see it would be nice if it worked and at the same time didn't compromise other uses too much
