True!  OTOH, for mere mortals like me, just making clear one's
assumptions about what the known behavior is supposed to be (and then
having a way to verify that they this behavior isn't regressing) is a
major boon.

Of course, when you stumble across an unknown unknown, you fix the bug
and write new a test case for it.  Then you continue marching backwards
into the future...
