Urgh, I guess if we are adding an interface which will live "forever,"
we may as well make it full featured & flexible, as long as the complexity
isn't out of hand, and I don't think it will be in this case.  So I'm at
least half inclined to go ahead & allow toggling it on and off under the
right circumstances, even though it goes against what I think is my better
judgement.  ;)
