https://w3c.github.io/mediacapture-fromelement/#dom-htmlcanvaselement-capturestream is pretty clear for canvas capture stream. "Content from a canvas that is not origin-clean MUST NOT be captured."

The wording is less clear from video element tracks: "The contents of the track might become inaccessible to the current origin due to cross-origin protections".
My interpretation is that content should never hit the consumer, be it web audio or peer connection.

Maybe the scenario is to introduce "trusted consumers" like the video element that would be able to get access to that content, other consumers never getting anything.
