Clarification: Our policy for patching back-branches is that the bug
has to affect many users, be serious, and the fix has to be easily
tested.
For a user-visible change (which this would be), the criteria is even
more strict.
I don't see any of this reaching the level that it needs to be
backpatched, so I think we have to accept that this will be 9.2-only
change.
