making sure I understand what you're proposing:

when you say "readable", is this shorthand for "copy media content into another object"?
>
> 2. MediaStreamTrack objects can be rendered if they belong to another origin, but only their size is known. 
"rendered" = "used for display in a <video> element"? (as opposed to being painted on a canvas?)

"known" = "readable by JS from the current origin"?
Size is if course not known for audio tracks. Is the frame rate (for video) or sample rate (for video) knowable properties?

Clarifying this seems to make a lot of sense, yes.
