This won't work at rpm level because you need to export tuples
(name,langage,priority) and rpm only understands monovalued properties

(ideally we should also export the family variant not only its name)

We sort of worked around the (name,language) tuple barrier by requiring a
package to only contain a single font family but for priority that can not
work.

You may try to hack around with font(:lang) = version but that requires some
serious thought to map fontconfig priorities to rpm versions (and what will
happen at upgrade time when a font is promoted/demoted)?

This is all a PITA that would be way more natural and less error-prone if
someone taught rpm to work with tuple properties. Because that's what fonts
metadata really requires
