I agree, the removal of the switch on iPad was a step backwards. However, you could at least map that switch to rotation lock. I personally leave my iPhone on silent always, and with Apple Watch it's redundant to hear both. I would prefer the option to map the iPhone ringer switch, to more than rotation and mute. Like how you can map the action button on Ultra, imagine opening the camera and snapping a photo, starting a voice memo recording, using the flashlight from your ringer switch, etc. It's a pipedream admittedly, like changing the stupid lockscreen toggles.
