Plone.app.iterate shallow copy

I'm wondering if anyone has ideas on how to implement a shallow copy when someone checks out a content item that is folderish...

The scenario is: you have a folder or say a folderish Dexterity content item that contains hundreds or thousands of items. Your site policy requires checking out a working copy, editing it, then checking it back in (maybe submitting it for review too).

There would be a registry setting that allows an admin to force shallow copy globally on check out.

The problem as far as I can tell is that the way it currently works is that manage_copyObjects() and manage_pasteObjects() are used to make the working copy and those are deep in Zope... probably best to let the Old Ones sleep...

    cp=(1, oblist)
    cp=_cb_encode(cp)
    if REQUEST is not None:
        resp=REQUEST['RESPONSE']
        resp.setCookie('__cp', cp, path='%s' % cookie_path(REQUEST))
        REQUEST['__cp'] = cp
        return self.manage_main(self, REQUEST)
    return cp


security.declareProtected(view_management_screens, 'manage_copyObjects')
def manage_copyObjects(self, ids=None, REQUEST=None, RESPONSE=None):
    """Put a reference to the objects named in ids in the clip board"""
    if ids is None and REQUEST is not None:
        return eNoItemsSpecified
    elif ids is None:
        raise ValueError('ids must be specified')


    if type(ids) is str:
        ids=[ids]
    oblist=[]
    for id in ids:

but I'd be tempted to add code that checks if the ob is contained and skip it if so... https://github.com/zopefoundation/Zope/blob/2.13/src/OFS/CopySupport.py#L208
