2 authentication with Zope 3s, and when we have replaces Zope 2
publisher with Zope 3s and when we have replaced the Zope 2 traversal
with Zope3s, and maybe a couple of other things.
At that point, Zope2 will more or less be Zope3 + App, DateTime, OFS,
Products and some other stuff. Then something more of a merge might
Up until then, we have a functioning system now, and I'm guessing the
benefits will not outweigh the work.
