And sort of a 3.1 option is to prepend a PEP 440 version epoch:

    https://www.python.org/dev/peps/pep-0440/#version-epochs

Challenge there is that, while Git can handle a ! in a tag name, PBR
doesn't know to sort that after implicit 0 epochs nor does a lot of
our release automation have the ability to cope with version epochs
and adding support for them would entail a lot of careful work and
thorough testing. Also having upstream epochs could wreak havoc with
downstream distro package maintainers, look confusing in
tarball/wheel filenames (hopefully all modern platforms are at least
not going to break when there's a ! in a filename), and so on.

The concerns were touched on in this thread from 2015 when the
versioning changes were going into effect:

    http://lists.openstack.org/pipermail/openstack-dev/2015-July/069085.html

Pretty unlikely to happen if you ask me. I'm just bringing it up
preemptively since odds are someone else with less history/memory of
the scenarios we discussed back then is likely to bring it up as a
silver bullet solution otherwise.
