I wasn't talking about neutron's jobs, but rather other networking
projects that use neutron + other networking projects... But I suspect
the same applies to them as well.

If I understand correctly, that risk only applies to consumers of "beta
releases" during the dev cycle (other openstack projects for testing I'd
What gets packaged/installed in terms of a release deliverable would
still be tested with dependencies pinned via stable branch contents, not
them from git source.

Is this correct?

I think we may have a special case here in neutron land as part of our
neutron-lib effort [1][2]. We are aggressively rehoming [2] common code
from neutron into neutron-lib and then consuming it in neutron and other
networking projects (currently 20 projects in total). Due to the volume
of code changes involved and the potential for cross-project
dependencies, testing only with tagged releases implies an extra step in
this process that could hinder velocity.

Am I wrong to think that maybe this special case could warrant testing
from git master source rather than tagged releases during the dev cycle?

Or perhaps we just start doing a lot more releases of these networking
projects during the dev cycle?
