Yes indeed.

Grok's OrderedContainer implements 
zope.app.container.interfaces.IOrderedContainer. This essentially 
specifies the updateOrder() method. This method will never be scalable I 
presume for very large sets.

Grok's OrderedContainer does not actually subclass the ordered container 
that already is in Zope 3 since that implementation uses a 
PersistentDict for storing the items. It does however subclass 
grok.Container that stores the items in a BTree.
