And, of course, a picture of your passport and driver licence proves absolutely nothing, except that you're able to upload a picture of a passport and a picture of a driver licence. Uploading a video of your face proves that, well, you have a face. It would be trivial to make the photo and video match with easily accessible technology.

At least where I live, governments don't really let a third party validate the info on a passport or even on a driver licence outside of a few regulated entities like banks - so they aren't doing anything useful with these photos, except storing them for the inevitable leak.
