If the issue is about `MediaStream.id`, it should be filed in https://github.com/w3c/mediacapture-main/ since that is where the attribute is defined as a UUID, and the Screen Capture spec doesn't (and can't) change anything about it. I also don't think this particular id presents a fingerprinting risk since it is never persisted (contrarily to deviceId).

But the title of your issue suggests you were talking about deviceId, not MediaStream.id - and while there is a deviceId in Screen Capture, contrarily to Media Capture and Streams, it is not exposed to JavaScript and hence is not fingerprintable (not matter its format, which is not defined by the spec).

I could also be missing something, so I would appreciate your guidance.
