Django debates user tracking

Well, it might be trivial to install some python-only library if you are using a virtualenv anyway. However I'm really glad that Fedora ships things like numpy, opencv, PyQT/PySide readily available. Also simplejson gets regular (security) updates which are too easy to miss if you just set up a virtualenv and leave it there.

Basically package managers like dnf/apt do a *way* better job than pip (with regards to keeping the system up-to-date). Oh, and they also ensure that you can actually trust the packages you installed. This is part of the reason why I really would like to see some combination of rpm/dnf (or deb/apt if they get there first) and virtualenv.
