The current users of python-barbicanclient are:
Package      : python-barbicanclient [python-barbicanclient!=4.5.0,>=4.0.0] (used by 16 projects)
Also affects : 16 projects
openstack/castellan                           []
openstack/cinder                              [tc:approved-release]
openstack/compute-hyperv                      []
openstack/heat                                [tc:approved-release]
openstack/kolla                               []
openstack/magnum                              []
openstack/mistral                             []
openstack/neutron-lbaas                       []
openstack/neutron-lbaas-dashboard             []
openstack/nova                                [tc:approved-release]
openstack/octavia                             []
openstack/octavia-dashboard                   []
openstack/openstackclient                     []
openstack/python-openstackclient              []
openstack/solum                               []
openstack/tacker                              []

But IIUC it's really only octavia and heat that don't work with 4.5.x

Looking at the change logs:

[tony at thor python-barbicanclient]$ git log --decorate --oneline
--no-merges 4.4.0^..HEAD
714fce2 (HEAD -> master, origin/master, origin/HEAD, gerrit/master) Support import modules from barbicanclient.client module
49505b9 (tag: 4.5.1) Workaround for importing objects from old path
ea509a5 Update api references according to refactor result
e0e3703 Add secret_type filter to CLI
f844a0e Updated from global requirements
a95c1a1 Update the documentation link for doc migration
51d8bfa Updated from global requirements
c497189 fix default version
3c7d909 Updated from global requirements
e599dfd Update doc references
2479529 import content from cli-reference in openstack-manuals
9af9169 rearrange the existing docs into the new standard layout
4eed5c8 Switch from oslosphinx to openstackdocstheme
439ee25 (tag: 4.4.0) Updated from global requirements
97906c8 Refactor barbicanclient

So all the changes look okay to me, assuming the 4.5.1 and 4.5.2 patches

Once we have the release I'll create no-op changes in all the affected
projects that depend on the u-c bump.

What concerns me a little is that we can't test this without a release
and once we do the release we're committed to some form of g-r
alteration with the impacts associated with it.

Would it be terrible to branch stable/pike @ 4.4.0 and leav all the
4.5.x stuff for queens?
