the handlers were written to use IObjectAddedEvent as some things in the
Zope2 world can't happen until an object has somewhere to be or more
pertinently this is the most common pattern. Adding the check is easy
enough but I'm interested in the general pattern here: should we be
looking at working with (and notifying) ObjectCreatedEvents? Or should
this check become standard?
