Most of the underlying specifications are REC, except for ODRL, vCard 
and SIOC on top of my head (well, and Web Annotation, which is "only" a 
Proposed REC for the time being).

Why does it matter whether the vocabulary is for a REC?

Also, I was not suggesting to make that a "requirement", be it only 
because I'm not entirely sure where to make this a requirement within 
w3C, to start with.

It makes sense to me to publish an ontology whose definition follows the 
same patterns as other ontologies published by this group or other W3C 
groups, but I'm fine if the group thinks this particular point does not 
matter.

Looking at some of the vocabularies listed there, I see published 
vocabularies without "rdfs:isDefinedBy" statements such as cal, EARL, 
geo, RDFa. These vocabularies seem to have been published earlier on.
