"If a user taps on a menu bar item, for example, it will display a larger set of controls optimized for touch."

This is a fascinating way to handle it. I'm curious to see how this applies to other parts of macOS

For example if you tap on an app icon in the Dock does it launch the app in touch-metrics mode?
