Please remember, Zope 3 core is not all the applications that use Zope 
3. In Zope 3 core, currently there's only one more layer than there are 
skins. This is not necessarily true for all applications that use Zope 3.

My point is to make people aware of this use case. It may be something 
we have to solve on the application side with tagging, etc, but it would 
also mean the framework is doing less for us than it is doing now, where 
we can just ask for a list of skins.
