Very true.  In Zope 3, that is the distinction between the "Zope" 
package and the "Zope.App" package.  Every Zope.* package, besides 
Zope.App.*, can be used independently of Zope.  So Zope.Publisher, 
Zope.Server, Zope.TAL, Zope.PageTemplate, Zope.ContextWrapper, etc. are 
all non-interdependent.
