Possible RDF Validator options change

Hello,

We are considering removing the option in the RDF Validator [1] labelled:
"RDF is NOT enclosed in <RDF>...</RDF> tags."  The option was originally
introduced a couple years ago when the RDF/XML spec said a serialization
could either be contained in rdf:RDF tags or not.  The spec has changed
to now claim that serialized RDF/XML "must be contained inside an rdf:RDF
XML element." [2]

I belive this means the option is no longer relevant.  Does anyone know
of reasons why we should not remove the option?
