There isn't much text in 4574 - the main point of the RFC seems to be 
that it's possible to create labels for streams before creating the 
stream. Those labels could be independent of the signalling mechanism.

The trend I see now is that most APIs and protocols people define (for 
instance Jabber/XMPP, JSON-based descriptions) have some kind of mapping 
to SDP, so SDP-as-a-format may not be so important (I heartily dislike 
multiple things about the specific format), but SDP-as-a-semantic 
becomes more important over time, and can't be ignored.
