If this were a general auth thing to get into the app, they would not have had to add a special library.
I wonder if it will be tied to the biometric boarding they've experimented with. I can't imagine much else you'd need a face photo for.
Maybe some kind of doc check like UA has, but actually verifying that it's you?
