> Thus the question arises... why not do SUIDs for uid==0?

Good question.  4.2BSD and System (III|V) both do.  If there's any
problem caused by that, somebody better let us all know real fast.
I suspect it was a philosophical decision - they may not have liked
the idea that running a set-UID program lost root privileges instead of
gaining them.
