I think the conclusion on the same subject for input devices was that
giving the drive-by web the ability to tell the number of devices you have
and of what type (video/audio) was a reasonable compromise between the fear
of fingerprinting and the desire for sensible user interfaces.

I hope we can make the same call for output devices; having those be
different would, I think, be confusing to the developer and to the user.

As for "details": Agreed.
