They clearly say “exceptions to this rule will be listed in the release notes” meaning that backwards compatibility is the rule. There’d be no exceptions if there was no rule hence I said they “should” be backwards compatible except for specific exceptions, which shall be noted in the release notes.
Not sure how this conversation is productive, but there's never been a X.Y release of django without noted backwards incompatible changes to my knowledge. Just imagine that djangos X.Y releases are semvers major releases, not much more to it than that.
It also very clearly states that there may be exceptions to the rule. So a package repository that assumes that Django follows semver is unequivocally doing the wrong thing, because Django is very clear that they don't (otherwise there would be no exceptions).
