No.

Bottom-line: When you encourage RDF agents to make *heavy*, adhoc
(i.e., unguided) use of the transport protocol to facilitate machine
understanding (semantics, etc..) you burden the transport protocol
unnecessarily.  This contributes to the scalability problem:

"..  when a resource is very popular and its use is associated with
attempts to get a representation, use of http: URIs can lead *in
practice* to a crippling volume of traffic on particular web servers."

Again, with a few words added to highlight the relevance:

"..  when a resource is very popular and its use (in RDF) is
associated with attempts to get a representation, use of http: RDF
URIs can lead *in practice* to a crippling volume of traffic on
particular web servers."
