Hang on a second here. I, like many others, wear multiple hats.

The things you listed that I help maintain - mock, testtools, etc -
are *not* OpenStack specific. They existed before OpenStack, and
likely will exist after. They have other users, particularly mock
which is very widely used.

Its entirely reasonable to say that known reverse dependencies should
be considered when upgrading packages, but that is in no way OpenStack
specific - and the release schedule of all of the things you listed is
entirely independent of OpenStack.

Its one of the defects of the single-version design of the archive
that we have this uncontrolled use of new releases of software thats
put into it, and - well, thats another discussion. We need to live
with it though.

So I'm +1 on "Check reverse deps aren't significantly broken before
uploading to unstable" as a general principle, not as an OpenStack
specific thing.
