Because you offer no evidence. :-) How can anyone accept a hypothesis
without _knowing_ it?

Yaaay!!! An argument about which rank should be given to a particular group!

What could cushion your shock if it demonstrates its holophyly? :-)

I hope Arctometatarsalia was defined later than Ornithomimosauria. Anyway, I
think care will be taken to produce this situation -- that, if
Arctometatarsalia is a synonym of Ornithomimosauria, it is a _junior_
synonym -- will be replicated under PhyloCode (remember: PhyloCode won't be
retroactive and will reset all priority of definition to zero). That chance
is probably smaller for Carnosauria, but at least it's defined so that
*Allosaurus*, _the_ carnosaur, always is a carnosaur; though I do think
Allosauroidea or even Allosauria look better.
