And my mates Ceres and Sedna! And Orcus, Makemake, Haumea, Eris (which started this whole deal), Gonggong, Quaoar, Salacia, Leleākūhonua, and at least 40 undiscovered Sednoids. Vesta, Pallas, Hygeia, and Interamnia probably counted at one point too!

At some point it stops being gatekeeping and is just another kingdom entirely.
