The project will build wheels first. The wheels generated tend to look something like 13.0.0.0rc2.dev10 when they're built because of pbr.

If someone is doing CD with the openstack-ansible project and they deploy mitaka once it has a final tag, then they decide to upgrade to run master, they could run into problems upgrading. That said, I think my team is the only team doing this. (Or at least, none of the other active members of the IRC channel talk about doing this.) So it might not be anything more than a "nice to have" especially since no one else from the project has chimed in.
