Zope 2.12 with its many changes is seen as too risky to introduce into
our current stable series or into any release that aims to be released
as final by the end of this year.

The conflict arises from Plone the product and its conservative policy
and the desire of a minority of community members aiming for latest and
greatest. Plone the product itself never steps out of the tight
boundaries of the Zope release. But whoever wants to innovate on top of
Plone using Zope or Z3C technologies often does.

The innovators are who speak up here and try to keep it possible for
them to work. But the vast majority of Plone users has no interest in
these and prefers the ultra-stable policy of the product. Plone has that
conflict of developer and end-user interest in many situations - this is
just another example of it.
