Exactly.

By the way, we used to have a very precise input method on mobile - the stylus. In the times of Windows Mobile (original Windows Mobile, not renamed Windows Phone) with resisitive screens. The information density of those 240x320 3" screens is hard to achieve even today - google 'SPB Diary' for examples. Combined with stylus, multi-level menus and physical QWERTY keyboards (with shortcuts!) that were the very efficient machines actually.

Maybe recent revival of stylus, thanks to iPad Pro will tend to abandon the 'huge control elements' UI paradigm.

Samsung with their S-Pen on Note models would have a really value-adding and interesting stylus-oriented UI (as an option) instead of awful TouchWiz for years, but they never did it.
