Yeah maybe. It wouldn't do any harm, at least.

I didn't do that in the patch I just sent as it felt like something we
should do or not do for all the bitmapset functions it's relevant for.
REALLOCATE_BITMAPSETS is meant to give us a stronger guarantee of
people forgetting to do this, as it would cause a breakage if there
were multiple pointers to the same set and only one of them got
updated.
