I have no objection, but I haven't pushed the infra team about the 
actual branch deletion because as far as I know, cinder is the first 
project to actually request removal, and I suspect all sorts of stuff 
will break.  I suggest we wait until at least after RC-time to give us 
all one less thing to worry about.

As far as avoiding breakage goes, I put up two patches to devstack so 
that it will check out the -eol tag of cinder/brick/cinderclient instead 
of the stable branch, but I suspect these only scratch the surface of 
what can be broken once the cinder project branches are deleted.

Sean suggested in an earlier thread on this topic [0] that instead of 
deleting very old EM branches that some projects have EOL'd 
project-by-project, we should just delete them wholesale across 
openstack.  That makes a lot of sense to me.
