Well, the point I was trying to make is that there may well be fewer
people depending on the current behavior than there are people for whom
the current behavior is wrong, only they don't know it because they've
not seen a failure (or not seen one often enough to diagnose what's
happening).
This is of course merest speculation either way. But I don't feel that
we need to necessarily treat rule behavior as graven in stone.
