Are there actually any RSS 1.0 extensions in popular use?  I note that
RSS 2.0 approach made it very easy for podcasting to catch hold, and
this may be a consideration when evaluating an extensibility philosophy.

This is perhaps wishful.  Most syndication tools do not support RDF
model at all, and simply read the RSS 1.0 file as XML.  Most tools would
barf given any of a number of isomorphic RDF models which stray even
slightly from the expected XML syntax.

Again, I would temper this -- they can consume the RDF graph, but not as
RSS (unless you meant to say "virtually all RDF-based syndication
tools").

How is this use case any different than using RSS (or Atom) as a
protocol for moving around audio streams, bittorrent pointers to TV
programs, and other payloads?  The fact that RSS can be useful with a
wide variety of payloads is evidence IMO that it defines a good
separation between the protocol and payload, and my suggestion would be
to treat RDF as an opaque payload exactly like any other.
