Switches are already ubiquitous on mobile UIs: https://developer.apple.com/design/human-interface-guidelines/toggles https://developer.apple.com/design/human-interface-guideline... But checkboxes and switches don't always make sense. You don't always have room for e.g. "Light mode <switch>". Every component that you give more room to takes room away from other UI. Rather than look at the obvious cases, the hard part is the periphery of what's obvious.
