You didn't hear it from me but this is surely abuse of inheritance?  
Time to call the cops and stand outside our houses in dressing gowns  
and slippers tutting and looking superior!

+1
It's not as if Folder's behave as content although it is perfectly  
reasonable in my view for Folderish objects to do so.

Indeed.

And IWorkflowAware should be implemented separately where required, he  
added quietly still working his way through Workflow code. I've  
written an almost generic Transition form for IWorkflowAware objects  
(the workflow should be pumped through the form). Any interest?  
Currently dependent upon adding ?form.workflow_action=xyz to the  
transition action which reminds me of add forms and suggests the whole  
thing probably needs, ahem, revitalising.
