Another usecase we have for it that we have are USB video capture 
cards that show up as UVC devices but are used as HDMI monitors rather
 than video content. In Chromium we allow webcam content to downscale 
(since good VGA is better than bad HD, and we like to preserve fluid 
motion), but for text content this completely messes up fonts so for 
screencast we drop frames instead.

For these USB video capture cards we have no (simple) way of knowing 
that it's not actually a webcam, so this hint would allow an 
application that is aware to configure the device differently. A 
device blacklist/whitelist seems like a bad choice, apart from being 
tedious/impossible to maintain, as someone could also have plugged in 
their video-game console and then screencast settings would be awful 
again.
