So a better assumption would be:

We don't know what people did with _objects, so _objects might be important.

Right?

That means: All Zope2 Folders have to be converted to Zope3 Folders with 
OrderSupport (what ever OrderSupport would look like in Zope3).

If that is the case, I can't see why the default Zope2 Folder can't have 
OrderSupport. Maybe you read the discussion I had with Shane about this 
issue
<http://mail.zope.org/pipermail/zope-coders/2002-December/002955.html> 
or ask him yourself.

I'm not sure if I did get all his arguments, but the point that 
convinced me is becoming weak.
