Well, ditto. I'm really unclear on why with-current-buffer is always
an appropriate substitute for (save-excursion (set-buffer fu-boofer)
...), for the same kinds of reasons I'm kinda unclear on why global
match data is ever a good idea. Not everybody programs in functional
style; you may have cause to call code which has nasty side effects on
the buffer you're explicitly working on.

I don't really see why. It would be the same as now except that you
don't do a final set-buffer. Whether that would be useful or not is
another question. Evidently you don't see it as useful, though, which
answers my question.
