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

[Oon-Ee Ng]

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
?
