Why not just dispense with all the extra language altogether?
As you point out, "*" is a valid basic language range, so we
don't need to explicitly allow it. And I don't really see any
reason to forbid "fr,*,en". It's logically equivalent to just
"*" and shouldn't cause any implementation burden. In fact,
forbidding it probably just means implementations have to add
a check to throw an unnecessary error.
