I think it's time to make python point to python3. I suggest setting
/usr/bin/python -> python3
and then using alternatives to make /usr/bin/python3 resolve to a python3.x.exe.

It should default to python3. Fedora performs this via an extra package
python-unversioned-command, containing just a symlink /usr/bin/python ->
./python3 as well as a man page symlink /usr/share/man/man1/python.1.gz
-> ./python3.1.gz. We could just do the same, no?
