It's not a nothingburger. An ID card has biometric information from years ago. Correlating a photo match with a ticket at gate check in gives confirmation for updating the stored id-face model, which means the recency and fidelity of the biometric data stored by e.g. the airlines or CBP is higher than that from the ID card. Random surveillance video in an airport probably can't be used to update records because you have lower confidence of a match absent the other known factor that confirms ID. Moreover, masks/face covering is a norm that will also help subvert ambient face ID and model updating. The data won't stay in the airport—the updated id-face model will be used in places where we expect or should expect more privacy of identity. We as a society could decide to limit the legality of this. As individuals we can opt out and likely make a small but meaningful difference in the recency and fidelity of our collected and shared biometric data.
