Not too many opinions thus far. :-) It basically boils down to this: Should 
the reject_if option only be relevant for creates and updates or for 
deletes as well?

I tend towards "yes", but a patch for this will change the behaviour of 
allow_destroy in conjunction with reject_if. Such an API change might cause 
headaches on existing applications. (A temporary warning if both options 
are set might be useful.)

Opinions anyone?
