I think one thing that makes an external stream deck work, is that it is a separate context sensitive device, that is mentally separated from the keyboard.

So when you go to the deck to perform an action, you mentally context switch away from the keyboard, so your brain is looking for different clues.

So even with a touch bar + function keys, the function keys stay in keyboard context, but the touch bar requires that switch in any case. Maybe taking your eyes to the touch bar is enough of a context switch, mentally.
