It sounds like you are suggesting we take the tool we use to ensure that
all of OpenStack is installable together in a unified way, and change
it's installation so that it doesn't do that any more.

Which I'm fine with.

But if we are doing that we should just whole hog give up on the idea
that OpenStack can be run all together in a single environment, and just
double down on the devstack venv work instead.
