I think it was not used by Zope2 itself - however, it's a feature 
provided by the framework that applications can use. I guess there might 
be features in a framework that the framework itself doesn't make use of.

Going down into the new ZMI project I find it to be the most 
light-weight approach without adding an extra dependency.
