I still fail to see how it is not possible to unlock with your passcode for the two use cases you mention.

I think I understand the point you are getting at, design for tricky situations and the normal situations will be easier, but I think you are failing to see that you cannot design for every scenario, eventually you have to weigh up the feature sets of two technologies and pick the best one for most use cases and users, which Apple obviously thinks is FaceID.

I think FaceID will allow features simply not possible with TouchID, and expand across the Apple product line, and to other manufacturers, to the point where in 5-10yrs time we just expect screens to recognise us. This is an important step towards this.
