And it’s defeated by someone just watching you unlock your phone in public once.

  As is a passcode?

    A passcode that you type in fast seems a bit harder to record than looking at someone who winks at their phone

  Except it isn't, assuming the tech works as described. Face ID uses a 3D reconstruction of your face (now we see where that Primesense acquisition went). You can't bypass it with a video, or a photo, because that would be presented to the phone as a planar surface. You could conceivably create a model of someone, but adding a gesture would make it incredibly difficult to mimic.
