Protopteryx actually lacks ossified uncinates as preserved.
Hou's illustration of Jibeinia's holotype has a few small structures that
might be ossified uncinates. Then again, they could be sternal ribs or
broken dorsal ribs. Also, we must take into account that Hou's
illustrations are hardly detailed, and quite possibly not accurate. In any
case, he doesn't describe such features.
The rib cage of Sapeornis' holotype is far too incomplete to rule out

Look forward to an update on my analysis VERY soon. :-)
BTW- David, I can't access my university e-mail account at the moment, so
cannot reply to the thread we had going (Dino-bird theory). Hopefully, I'll
get it working soon and we can continue.
