Sure. But currently font cache remembers not the "best match" X but
the vector [X0 X1 ... Xn] which was used to select X for the last time.
Under some circumstances (in particular, when a lot of fonts are loaded),
font cache tends to grow too much (see
http://lists.gnu.org/archive/html/emacs-devel/2013-10/msg00740.html).

This assumption is wrong. Although explicit font change is rarely done by the
most of users, new fonts may be loaded quite often - to display an "unusual"
character which has no glyph in current font, to display something under
M-x customize, etc.
