Ok. I don't really care that much.

Yes. We could, for example, add another Product to Zope 2.8 (e.g. 
'BridgeInterfaces') that contains a configure.zcml file that does this; 
that way the ZCML file gets automatically picked up by Five.

I leave it to you and the others to decide whether to use this approach 
(add additional ZCML files to Zope 2.8) or whether to modify Five. I 
guess your suggestion is slightly more elegant.

Your kupu login will work.
