Comment (by Mariusz Felisiak):

 > I'll let Mariusz and Carlton chime in here. This is a data loss issue so
 [https://docs.djangoproject.com/en/4.0/internals/release-process/ it
 should theoretically qualify] but the issue has been around forever and
 only happens for uncommon model structures so I'd be wary of introducing a
 regression via a minor version if this was backported and possibly cause a
 different kind of data loss issue.

 IMO, the risk of introducing another regression is too great. Moreover it
 was reported after Django 2.2 EOL (April, 1st) so it wouldn't be
 backported regardless of our decision.
