OTOH I don't think that the concept of the application controller should
be mentioned in zope.traversing which is about something else entirely. I
do think that this sounds like the perfect reason to introduce that
registry: Some interface IEtcTraverser or similiar might be introduced
against which named subscription adapters might be registered. Then,
zope.app.application could register its own code to handle the "process"
and "applicationControl" names.
