We may want to mirror pypi but for other (performance/stable access)
reasons so that is a separate thing.

OpenStack spent some time capping Python versions of things for this
reason, and has reverted to only doing that in response to specific
breakages, like pip 19.0.  In this case it may have been fixed before
some folks noticed and the only result with be adding "!19.0,>=19.0.1"
in the global-requirements file for pip. (Actually, as of my writing
this no change has been proposed for pip, probably because 19.0 is not
going to be picked up by anything automatically with the release of
19.0.1).

The reasoning is that you want to know about things like this sooner
than later and work to get them fixed, or identify workarounds,
otherwise you find yourself in a hole of debt to move forward, and
once the mass of interlocking dependencies move far enough it can
become a pretty big hole.

Once you enter stable release territory that changes as you often do
not want to move forward and break the stable release, so our Pike
build may have wanted to hard-cap pip, but that is a short-timers
issue for us now.  Once we're only on master I think following
upstream is better in the long run.
