But if what we want is a specific font, then adding its family will
produce unreliable results, and might well yield a font we don't want
in some setups.

IOW, what you suggest was already tried, and found to fail in some
cases.  We are trying to fix those cases, so using the same technique
we already know is faulty sounds unwise to me.
