Perhaps that should change? :)

I'm quite concerned that the "use-the-eggs-as-needed" approach, taken to 
its full potential means no synchronised releases and ultimately degrade 
the "library user experience" (how do you know where to start? how do 
you know what works with what?) for those not already experienced with 
Zope 3.

However, eggs are great. They make it much easier to manage your 
dependencies. Things like entry points and egg script wrappers are very 
powerful. The Cheese Shop as a way of making releases is really pain 
free and much more conducive to making frequent releases. We've embraced 
eggs in a big way for Plone 3, and found the experience generally very 
postive.

FWIW, I've found it tricky to use things like z3c.widgets (or more 
accurately, a part of z3c.widgets, but that's a different story) because 
there was no egg to find, download and let buildout install for me.
