Somewhat out of date here:

My LATEST matrix (the SVP 2K matrix, not the modified Gaia one which will
appear in the Ostrom Symposium) finds _Caudipteryx_ as closer to
Oviraptorosauria/Oviraptoroidea (= Caenagnathidae + Oviraptoridae) than to
Therizinosauroidea, but outside a _Microvenator_ + Oviraptoroidea clade.  In
fact, when _Nomingia_ is included, it fell closer to _Caudipteryx_ than to
other oviraptorosaurs!

Oh, and to answer the original question:
The status of _Caudipteryx_?  Still dead... :-)

P.S. Remember that Gould is a specialist on evolutionary theory (in general)
and on late Cenozoic pulmonate snails (in particular): the details of
coelurosaurian anatomy and relationships are not part of his expertise,
hence his confusion.
