They could add it and leave t]Touch ID in as well.
You could still have Touch ID so it would be an addition
Much better than a bigger bezel, whic peopel would complain about, or a punch hole.
I don’t get it. They could easiy add TouchID to the power buttion on all mobile devices as an option without deleting Touch ID.
But very practical and secure; and not bypassed by say law enforcement simply holding your phone to your face. It’s a computer not a work of art, and the focus needs to be on function, not form.
