Well, considering all the discussion about whether an RDF URI that 
identifies an RDF resource should return anything, and if so, what... 
and the fact that some RDF URIs are likely not to be GETTable and when 
they are, may not return RDF... how are we to know when an RDF 
resource's URI is to be treated in the favored way and when it is not?

Since the answers to these issues is not spelled out in the RDF spec 
package, nor really in the other specs you mentioned, it will have to be 
settled by common usage based on what seems sensible (like your 
argument) - to me, that is by convention.
