I do not argue with you that Zope3 is "different software than Zope 2".
What I argue about is "Zope 2 is an application".
I have seen hundreds of applications built on top of Zope 2, long
before someone thought about Zope 3. I interpret this as:
"Zope 2 is not an application but a web application framework".
Recently some applications make not only use of Zope 2
but also of Zope 3 (prominent example is Plone 3).
But Zope 2 itself is still only slightly dependent on Zope 3.
This statement is very confusing, given that nearly all of Zope 3 ships
with Zope 2 since 2.8. So in fact a Zope 2 release depends very much on
a Zope 3.
It may be true that not much of the Zope 2 machinery uses Zope 3 (but if
you look at Zope 2.10+, you'll see that core components such as the
ZPublisher have been changed to look up views), but certainly a lot of
applications that are built with Zope 2 use the Zope 3 libraries that
ship with it, as well as the integration layer Five. This makes the Zope
3 libraries as much an integral part of Zope 2 as the "old" packages.
