Which Pokémon Deserve a THIRD Branching Evolution?

So recently with Applin we saw a Pokémon that wasn't too special, until the Gen 9 DLC showed us that it actually has a Third branching path of evolution! Until now the only Pokemon that have had more than two branches were Eevee and Tyrogue, so quite an exclusive club, however Applin didn't stop there being able to evolve AGAIN after that!
This was truly unprecedented, but now that we've seen it, who's to say that this couldn't happen again? So which other Pokémon could pull off getting new family members added after the fact, and join the 3 branch crowd?
