FWIW, it seems to be consensus in the Zope community that "Zope3" was a
misnomer, reflecting a vision for the software (serving as the
replacement / successor to Zope2) which it didn't grow to fulfill.

At this point, the "reusable" bits now form a collection of
separately-released packages referred to as the "Zope Toolkit,"[1] which
is intended to be used by Zope2, Grok, and the folks still running the
"pure" Zope3 appserver.

A lot of the work involved in this effort has been in disentagling the
dependencies among the various packages, precisely so that they can be
used piecemeal, without pulling in all of the stack.
