Because most well-known Mesozoic dinosaur genera are already monotypic. It's
kind of ridiculous that almost everything has two names.
I think erecting subgenera is bad policy for another reason: I'd like to just
use clades and (grudgingly) species as formal taxa. Subgenera present a problem
when converting to clades: namely that a lot of them are homonymous with
another taxon (the genus).
Clades within clades that were converted from genera, though -- that's fine.
