Keep in mind, that OpenStack inside of Debian is just Thomas for a
variety of reasons. Others have tried to help and are trying to help
and aren't really able to stick around.
The effects on downstreams shouldn't be significant. People packaging
Ceilometer likely already package Gnocchi. How those packagers choose
to consume deliverables is what will change. In a similar vein,
OpenStack Infra has a signing key for each release cycle that Gnocchi
is likely currently signed with when tarballs are released. You may
receive complaints that new releases aren't verifiable in the same
way, but that and needing a decent MANIFEST.in (assuming you're also
dropping your usage of PBR) will probably be the largest problems
(beyond where downstreams get the actual deliverable).
In the end, I think this should inform your decision but not make it.
