Comment (by Simon Charette):

 > I'm skeptical that Django should facilitate running multiple Django
 versions concurrently.

 I think we should allow find a way to multi-node upgrades to happen just
 like we do with `pickle_version` for anything that uses `pickle.dumps`.
 Large project Django upgrades are often
 [https://landing.google.com/sre/workbook/chapters/canarying-releases/
 tentatively deployed through canarying] and eventually rolled out to
 multiple nodes gradually (pods, dynos, etc.).

 Not having a way to a graceful roll out of a version should be considered
 a release blocker IMO.
