ztapi.provideUtility(interface, component) is discouraged and should go 
away. I didn't do this for Zope 3.3 because of a lack of time.

zope.component.provideUtility(component, interface=optional) is a 
convenience spelling for:

   zope.component.getGlobalSiteManager().registerUtility(
       component, interface=optional).

The order of arguments is the same. I think Jim wants the convenience 
functions in zope.component (provide*) to go away in favor of the 
explicit spelling through the global site manager. I think that before 
we do that, we should first abolish the term "site manager" from the 
zope.component API (because we don't call it site manager anymore).
