With one eye on the calendar, I think the right way to proceed is to
push this to all branches (including 14) soon after next week's
releases.  I feel this is too high-risk to shove in just before a
release, but shortly after one is ideal since we'll have 3 months to
find out any problems.

I would support omitting 14 if we were down to just one remaining
release for it, but we'll have 2 (August and November).  So there
will still be an opportunity to fix things if there's an issue
that manages to escape notice until after the August releases.
