Wouldn't this potentially examine many more fonts?  For example, if all I
want is a 'bold' version of the same family as the default face's font,
Emacs currently can find it almost immediately, by considering only the few
fonts of the same family.  Whereas with your proposal, it will start from a
"clean slate" every time and will need to examine many (if not all) of the
fonts on the system to be sure score-only matches will find the best
candidate.

Also, font_score only scores the numerical attributes, so how do we assess
the "score" of matches for :family or :adstyle?
