I would not go so fare. Maybe some use cases may want it and RIF v 3.0 
should cover it.
However, we should start with state of the art in industry rather than 
science fiction of
academia or over guidance through fancy features of use cases (carefully 
designed by
academics to justify their latest invention).

A big design flaw of RDF was to design it in a way that it needed to cover 
all aspects of
a certain use case. We still suffer from this overkill which made it much 
more complex in
regard to what is needed and can be handled in most cases.
