[Zope-dev] CopySupport bug or feature?

I have been developing some classes that need to know when they are copied or moved. I have been achieving this by adding my own versions of _notifyOfCopyTo, _postCopy, and manage_afterClone. Everything works as expected when you copy / paste an individual object. However, I have recently been made aware of a problem with this approach: if you copy not the object itself, but rather a folder containing the object, only manage_afterClone is called. In looking through OFS/CopySupport.py and OFS/ObjectManager.py, I discovered the source of the problem: manage_afterClone is called recursively on ObjectManagers, but _notifyOfCopyTo and _postCopy are not. Is this intentional? If not, I'd like to check in a fix. Geoff
