The fact is that right now, today, we still have code that relies on Z2 interfaces. Not just in third party products - current Zope2 releases rely on Z2 interfaces in some places as well. Some of that code has no Z3 alternative either. I find it very hard to believe that you want to silently break all that code. Whatever happened to our N+2 deprecation policy. If you insist on going this path we need to start adding deprecation warnings for the Z2 Interface class *now*. > Plone is already going to have to do this to work with CMF trunk, > because the "bridge" code which provided BBB Z2 interfaces is now gone. I've done that work on trunk already - it took a lot of work and was quite painful. There are probabyl still a few broken things that try to use Z2 interfaces.
