Sure mate, can you probe that?
I can probe that previous front facing cameras were hackable. And that alone is a reason to cover it, whether it has to do with the whole face id tech or not, part of it is still the front facing camera.
And of course you can ‘probe’ that the Secure Enclave is hackable, which is a different thing than the cameras. But the argument is that if both TouchID and FaceID data are stored in the same place then they’re both equally vulnerable (or invulnerable).
