Meh.  Nobody looks at minor release notes to find out what will happen
in some other minor release.  Moreover, the sort of people who might
be adversely affected are probably not absorbing every minor release
right away, so they'd very likely not see the advance warning anyway.

Hmm, well, we're certainly not making this change in pre-v10 releases,
so I'm not sure that changing v10 will make things much easier for your
future self.  But it's unusual for us to make back-patching decisions
on the sort of basis I proposed here, so I'm okay with just going back
to v10 instead.

If nobody else has weighed in by tomorrow, I'll backpatch to v10.
