Yes. But for the most part Christian is talking about stream/channel 
usages that have not yet been defined. When the are defined, they could 
be done so using channels or something else. The main constraint here is 
enabling this stuff to work with webrtc.

I think that constraint is effectively forcing the use of the data 
channel association usage.

And this is all hypothetical because draft-ejak is far from complete. 
So, if it goes forward at all it may end up different from what it is now.
