“Let the wookiee win”. Race/species in the star wars movies exists to signal extreme character traits. Chewbacca isn’t just a big, strong guy, he’s a wookiee. Jabba’s not just a fat, slimy guy, he’s a Hutt. The encyclopedic impulse to systematize things doesn’t fit well with that, the Star Wars universe doesn’t operate on “world building” logic.
