-1, as we should leave the option to using content-negotiation for 
returning RDF (*instead* of HTML) rather than RDF within HTML.

RDFa can be a bit hard to implement, depending on the template 
mechanisms on the server side. It shouldn't be up to the spec to mandate 
that RDF is within the HTML or alongside it (with a different content-type).

In addition, while I support the fact there SHOULD be an HTML 
representation, this is actually not necessary for the protocol to 
function, whereas narrowing down the RDF formats is.
