Which implies that this wouldn't do anything to diminish facial-recognition from consumer devices (e.g., facebook auto tagging, Google Glass, etc.)?

Try filming an IR remote control (while pressing a button) with your phone's camera. It'll light up. I think it's pretty cool actually :) (might need to do it in a dark room, depending)

I suppose the GP was talking about actual non-phone photo cameras?
