In Zope 2 land we've been using local adpater registrations quite  
successfully, actually:

* five.customerize lets you "customize" template-based browser views  
by creating a persistent PageTemplate and registering that as an  
adapter locally.

* plone.portlets, the new portlet system in Plone 3, registers  
content provides locally

* kss.core registers a local event handler just for AJAX views
