Well, we didn't bump the soversion (nor touch the documentation)
in commit f6a756e4, which is basically what I'm suggesting we ought
to revert. It was nothing but a quick hack at the time, and hindsight
is saying it was a bad idea. Admittedly, it was long enough ago that
there might be some grandfather status attached to the current behavior;
but that argument can't be made for changing its behavior still further.
