All of your hard work is very much appreciated. I don't understand what
your assertion means though. We don't pin things. However, our users end
up "pinning" when they install via pip, and our distros end up "pinning"
when they deliver a version. Without any indication that urllib3 is in
the system, they will fail at any cursory version audit that looks for it.

I'm not saying either way is right or wrong either.. I'm suggesting
that this is a valid, proven method for large scale risk assessment,
and it is complicated quite a bit by vendored libraries.
