Re: [mediacapture-main] Clarify getUserMedia({audio:{deviceId:{exact:<audiooutput_device>}}}) in this specification mandates capability to capture of audio output device - not exclusively microphone input device (#650)

@guidou We must have posted at the same time.

The capture of "Monitor of ..." devices is via entries exposed as audioinput by enumerateDevices, as it should be.

Again, do not care what technical jargon is used re inout or output. The use case is capturing only audio output from the system, not capturing microphone input where audio might be playing in the background.

Firefox does provide a means to capture `"Monitor of <device>"`. Whether you call that an input or output device is immaterial to the observable result: capturing audio output from the system, which Firefox provides a means to do simply by exposing `"Monitor of <devide>"` which you appear to be against implementing at Chromium, Chrome, for an unknown reason, which would tentatively resolve this issue.
