I think I was guilty of the same misunderstanding - apologies Tom! Thanks Peter for calling that out explicitly. For my for my part, gut feeling is that MacOS major releases will be similar to any other OS major release, which may contain updates to collation algorithms and locales. ISTM like the same thing PG is looking for on other OS's to trigger the warning. But it might be good to get an official reference on MacOS, if someone knows where to find one?
