Ah, I considered it a good thing to have one less place where
a particular typeface (well, in this case an alias) is specified.
I think of fixed-pitch, fixed-pitch-serif, and variable-pitch as places
to pick a family so other faces can inherit from them by default.

Put another way, one would only have to change one face to change the
monospace serif, instead of however each face specifying :family
"Monospace Serif" or some other typeface.  Though, perhaps I'm
misunderstanding face-font-family-alternatives.
