By luck, we now have a moderately well-educated guess about that
from Paul Eggert himself [1]:

: Probably NetBSD will go first as they tend to buy these changes
: quickly; maybe six months from now? Debian and RHEL probably a couple
: of years. These are all just guesses.

Based on that, I'd say that assuming v12 and earlier won't have to deal
with this issue does indeed amount to sticking our heads in the sand.

I don't intend to do anything about this until this week's beta wrap
cycle is complete, but I'm still leaning to the idea that we ought to
back-patch something.  Maybe the "something" could be less than a
full posixrules-ectomy, but I'm not really satisfied with any of the
other alternatives I've thought about.
