supposedly there are replies to this but I the W3C DB doesn't have them and I don't have the emails either. Anyways:

I am not sure MUST-> SHOULD solves the problem, because it does not give any useful guideline regarding the semantics of a relation 
without a role.

I would be happier to see  /default/ roles be defined for these relation, which can be overriden.
