Given that I and Greg Paul and a few others are largely responsible for that,
here is the reason:
What positive evidence is there that Podokesaurus is in any way, shape, or form
more closely related to Coelophysis & company than
to (for example) tetanurines? Or basal to neotheropods?
The characters originally used to unite Podokesaurus, Coelophysis, "Syntarsus"
& friends was: little theropod that lived before the
Middle Jurassic. Not really a strong case for monophyly there...
