Because it provides traversal adapters needed soley by zope.tales.   
Keep in mind that these adapters are currently for interfaces defined  
by zope.traversing, but these interfaces are only (or should only be)  
used by zope.tales.  Of course, these adapters could be moved  
elsewhere. In fact, it would be best to move these adapters to  
zope.tales as well, as they will work for any mapping object, not just  
containers.

There are also publishing adapters in zope.container that could  
probably move elsewhere, since they too will work with any mapping.

I suspect when I really wade into this, I'll be able to propose some  
other cleanups.
