Just to be clear, we didn't add rules about coinstallability to make
*our* upstream lives easier. We did it so that downstream distros
don't have to provide and support multiple versions of various
dependencies. What you're in effect recommending is that we stop
supporting installation within traditional GNU/Linux distributions,
since only package management solutions like Docker or Nix are going
to allow us to punt on coinstallability of our software. You're
*also* saying that our libraries now have to start supporting users
on a broader variety of their own old versions, and also
support/test working with a variety of different versions of their
own dependencies, or that we also give up on having any abstracted
Python libraries and go back to re-embedding slightly different
copies of the same code in all OpenStack services.
