Nobody uses pictures for identification. Not alone. In combination with everything else, maybe, but being French, I can even assure you that in most of the cases, people don't even look at your photo when checking your ID. They're always outdated, took in a weird lightning, and with a terrible quality.
From an administration point of view, whether you took a picture of your face and mapped it onto a 3D model, or just gave them the original picture makes zero difference. Last time I renewed my card, I gave them four years old pictures, I looked totally different, and they do not give a damn.
Identification through only a picture was dumb in 1985, and still is.
