Doesn't it makemore sense to prioritize by definition rather than name?
For example, I could claim Amniota is the correct name for Alvarezsauria
by redefining it to {_ALvarezsaurus_ > Neornithes, _Ornithomimus_}, just
as you claim AVes is the correct name for Ornithosuchia by redefining it
to {Neornithes > _Crocodylus_}
