Yes.  I think that, basically, the fit to height/width commands are
pretty useless -- nobody wants that, because it'll inevitably make some
images impossible to view.

The two cases that make sense are "scale down so I can see the images"
and "both scale down and scale up, because I want to see as much detail
as possible".

Sure, or a "don't scale up more than 200%", perhaps.  That's less
finicky, I think.
