Luigi - Thank you. I understand the tradeoff. 

OK, I have to manage this manually. What is the best way?

Is there any way to query the schema and find out which objects have fields 
that reference a particular class? (so that I can NULL them and then remove 
the class)

Regarding using Graph type: yes, maybe. But I really like the simple dot 
notation as it works with LINKs. I think it is very elegant. (I take my 
syntactic sugar wherever I find it)
