This was very p[reliminary. I've made a number of changes since then. :)

Why would anybody want this?  The new code is to support people who want to
use ZODB 3 and ExtensionClass together.  I though that set was the same as
people who want to use Zope.  When it's ready, this code will appear on the
Zope head and, later, in Zope 2.8.

I should note, however, that we'll be renaming the ZODB "Persistence"
package to "persistence". The "persistence" package will have the new-style
non-ExtensionClass persistent base classes. A new "Persistence" package
will be created that provides persistent ExtensionClass base classes.
