I sure hope it remains. I actually do use it, at the very least to launch the camera quickly and shoot quickly. I don’t necessarily adjust the settings though like apple was hoping more people would do. I’ve said this in another thread, but for those who don’t want to use it, they don’t have to. Nothing was taken away from the phone with the addition of this button. You can still use the camera like you did before the button existed. The Touch Bar on the mbp, on the other hand, ironically lost a whole row of physical buttons in lieu of a touch screen! I think what these two features do have in common is they both brought out complainers who hate change. You can’t make everyone happy with the Touch Bar, but you can with this camera control button. It’s totally up to you whether you want to use it or not.
