Martijn was faster than I thought :(

That's the point I missed!

So we just need code like this at the end of Five.interfaces:

try:
     # override IObjectManager with Zope 2.8 interface
     from OFS.interfaces import IObjectManager
except ImportError:
     # monkey patch Zope 2.7 OFS
     ...

Right?

Fine. I no longer think we need to break backward compatibility.
