I understand, the question is about *you* as a user.

So, can you explain why?  Also, is that really the only case where you
want mouse-face to look different?

Because adding umpteen customization variables for all the cases where
some user might want to change a face makes no sense.  So if there's
a good reason why this particular case is likely to happen to many
users, a customization variable might be justified, but otherwise having
a generic solution (e.g. face-remapping) seems quite sufficient.
