This view is actually consistent with the normative behavior for GRDDL
that we settled on with regards to content negotiation:


In the case of GRDDL, the 'maximal' GRDDL result (the RDF merge of the
renditions of each of the representations) is an acceptable rendition
of the original IR.

With such an allowance, a GRDDL-aware agent would not be able to
assume much about the IR behind the RDF rendition.
