"Haven't finished reading this thread yet, but, as an aside, what might be
so
peculiar about this? It is pretty close to what the
segnosaurs-are-theropods
school says happened to the segnosaur foot."

        Come to think of it, yes, it really is...but if the
arctometatarsalian condition is independently derived in the various
"members of the Arctometatarsalia," then segnosaurs still make nice
theropods...we just have to disband the Arctometatarsalia as it's currently
diagnosed (that is, many of the members may still form a monophyletic
taxon, but the arctometatarsalian foot condition isn't a good
characteristic to diagnose the group).
