What does "an interoperable way to request media and encodings" actually mean?

[vasilvv]

I am not entirely certain by what's implied by that. "requesting media" feels like something that would belong in the name/receive protocol, since requesting something requires a name?

I agree; it's too vague. I would even think establishing a connection is enough to "request media".

I'm not sure if the draft is trying to imply pull versus push and/or if there's some capabilities exchange. But I would argue that neither are required, as they can be handled by a higher layer (similar to WebRTC).
