Python 3 only images are possible -- dib has a whole "dib-python"
thing for running python scripts inside the chroot in a distro &
version independent way -- but not with the pip-and-virtualenv element
setup we do as that drags in both [1].  You can go through a "git log"
of that element to see some of the many problems :)

OpenStack has always managed to tickle bugs in
pip/setuptools/virtualenv which is why we go to the effort of
installing the latest out-of-band.  This is not to say it couldn't be
reconsidered, especially for a distro like Fedora which packages
up-to-date packages.  But this would definitely be the first
port-of-call for anyone interested in going down that path in infra.
