On the other hand, there's a long list of names formerly used for
paraphyletic taxa which are now, at least sometimes, used for clades,
including Synapsida, Therapsida, Cynodontia, Dictyoptera, Blattodea,
Mecoptera, Osteichthyes, Sarcopterygii, Saurischia, Theropoda,
Coelurosauria, etc. Should we have renamed all of those?

Personally, I find the name "Cetartiodactyla" unnecessary, unless
pan-cetaceans are the sister group to pan-artiodactyls. Why not just
say cetaceans are (or aren't) artiodactyls?
