It's also worth noting that these system fonts set all of the
subproperties of the font property, so that you get not only the
family of the system font, but also the size, weight, style, etc.,
which could then be individually overridden (or not) by the
longhands.

I could certainly believe that the current list of system fonts
there doesn't make sense in today's world; Gecko has long
implemented an additional list [1] that were prefixed versions of
ones in earlier drafts of css3-ui [2], but have since been removed,
and some of these were widely used in the Firefox UI and in our UA
style sheets for form controls and for XUL.

These have been implemented in Gecko since its early history,
although in a reasonably conformant way only since 2007 [3].
