Apple is reportedly working on a new iPhone control method.

A case with touch-sensing layers could change how you interact with future Pro models.
It is beneficial to provide more capabilities for Pro devices.
I believe that offering Pro users additional choices is a positive move, even if the accessory is expensive. Some customers will always want the latest or most advanced add-on regardless of cost. While the functionality of this touch-sensitive case remains unknown, it would enhance the Pro product line.
This case could potentially substitute the functions of physical buttons. Upon attachment, the iPhone could recognize the case and redirect controls to it, enabling taps, presses, or sliding motions to activate system commands. However, confirmation awaits an official release from Apple.
