Is there a particular reason that nobody is interested in letting the
warning be about the case that is supposed to be problematic, rather
than about a number of _intended_ parts of the behavior?

The problem seems more like

Warning: `save-excursion' will preserve point and mark in the current
         buffer even if set-buffer does not actually change buffers.

So why do people want to warn about non-problems and/or utter nonsense
(like the current "save-excursion defeated by set-buffer") all the time?

What is wrong with warning about the problem itself?
