I would recommend *not* hacking on the CMFCore product itself, but
rather create your own product and import what you need from it.
Modifying the CMF sources puts you into no-man's land, since we can't
try to reproduce your problem.

That interface (which is a Zope3 interface) is actually created
on-the-fly via a <five:bridge> directive in CMFCore/bridge.zcml, with
the same attributes / methods as the Zope2 version in
CMFCore/interfaces/portal_workflow.py.

This is the bridge.zcml in CMFDefault, right?  The CMFCore interfaces
are bridged in CMFCore/bridge.zcml.
