Nit clarification: let's call it RDO Trunk repository (Delorean is a
tool, recently renamed https://github.com/openstack-packages/dlrn )

It is not what happens, there are separate repositories for packages
built from master and stable branches but it is still confusing, and
I'm not sure why is such a big deal to just push one empty commit with
Sem-Ver: api-break when we have that nice PBR automagic ?
Previously pre-versioning was used and version had to be bumped
explicitly in setup.cfg when opening master for the new version e.g.
https://review.openstack.org/#q,Ib634eb7acb64ff1d7be49852972295074b11557a,n,z

Another example (not release:managed project but still) where we have
this confusion is gnocchi:
openstack/gnocchi > master $ python ./setup.py --version
2.0.1.dev61
openstack/gnocchi > stable/2.0 $ python ./setup.py --version
2.0.3.dev13
