It is very much a goal of Zope 3 to allow Python-based content adding; in 
fact, I am never adding content via ZMI these days. The closest I get to the 
ZMI is the Sample Data generator that creates a full application for me. By 
the way, much thanks to SchoolTool, Roger and Juergen who have developed this 
concept. We also use the configurator to configure complex content objects.

So to answer your specific question: There is an event fired when the database 
is opened with the root. See zope.app.appsetup.bootstrap, line 193. Hoever, I 
agree that an created and add event should be created for the root folder in 
the same function. Could you file a bug report, or even better provide a fix 
with test? :-)
