Good idea. Let's release a 3.9.x (or a 3.10) that does that as soon as 
possible.

I'm not sure I understand how Chris' zope.registry change has something 
to do with this API, perhaps I missed something? I agree that we could

in the trunk right away, as this documentation should be useful for 3.x 
as well, at least in terms of transitioning existing code.
