The use case which bothers me is similar to bug#51768, where users
specify certain weight or width because they like the appearance of
the resulting font, and expect Emacs to come up with the exact match,
not the best approximation.  When the family value actually names a
font (i.e., it is a very "narrow" family), that should work even if we
relax the numerical attributes, but if the family is much more
general, like "Sans Serif", the result could be different because we
still return whenever we find a first valid "approximation".
