At some point in time we requested bugs to be filed about quirks, with
EDIDs attached, so we could look at them later, and maybe remove the

The headset non-desktop thing started off as a quirk, but since then
we've added both Microsoft VSDB and DisplayID primary use as ways to
indicate this without quirks.
