Moving the languages into cultures helps, to some degree. At least now everyone raised in the "Deep Dwarf" culture knows common, undercommon, and dwarf...
But what is "Dwarf" as a language except an example of a racial monolith spoken across the dwarf-related cultures?
The VRC cultures all give you "Common, plus another language" or two. Or three. Or whatever. But what are those languages? Dwarf, Elf, Auran, Gnome, Minotaur...
Which are the same across every planet, because no matter how far apart elves are in the galaxy they all speak Elven in the exact same way.
