Just like Apple would never backtrack on a design like the old iPhone 4 using glass for the back of the case?
Just like the headphone jack, right? Because Apple’s not stubborn and it totally makes sense for them to backtrack on device features like that...
Honestly, if FaceID works as promised, why would you even need TouchID? There’s no added benefit unless FaceID is a total failure, and even if it is (which I wouldn’t bet on), Apple would probably throw money at fixing its issues rather than roll back their devices to what they are already treating as an inferior solution.
