I would argue a bit of both.  Zope 2 can be a giant egg without much 
difficultly enabling use of easy_install and dependency management in 
relation to that egg(think of how products depend on a version or  point 
version of zope2).  As an egg friendly installable, it can then be used 
in egg recipes etc.

it also lets us start teasing parts of zope2 out of the monolith of 
zope2 their own eggs(ZTC comes to mind) so they can evolve at a rate not 
controlled by the zope2 release process.

Since it is possible to match dependencies, releases can be built from 
egg recipes dynamically rather than cumbersome bundle linking.  I'm 
guessing this would make release management ultimately easier and more 
consistent; a recipe would simply match all stable and compatible eggs 
to the zope version that needed them.
