Not necessarily. The notch’s height is to accommodate Face ID -which is not just the simple front camera. I am proposing that they scrap Face ID, incorporate Touch ID either under screen or on the side button, and only house the tiny front facing camera that would be in the hole punch design in the bezel instead.The bezel would increase by the height of the notch, so the screen would either extend only to the bottom of the current notch, or the phone height would increase by the height of the notch.
