[aur-general] python-foo and python2-foo - should they conflict?

Was just trying out some python packages and I realized I can't have both the python and python2 variants installed at the same time for python-networkx. Of course, there's conflicts with the license files and perhaps documentation, but other than that I wonder whether there's a use-case for having both installed (I'm in an academic setting, and I use both python3 and python2). Should I simply custom-PKGBUILD such issues or does it make sense to have, for example:- 1. python-foo provides all files shared between python3 and python2 variants 2. python2-foo depends on python-foo ?
