I feel you’re missing the point here. Many power users opt to use the keyboard as the primary way of interfacing with the computer, and any change to that interface is highly disruptive and causes huge losses in workflow efficiency. This is the real complaint about UI changes - they ruin efficiency. Using the keyboard is much more efficient that using the mouse, as the mouse is an imprecise input device - it requires a feedback loop to operate (you move the mouse, see where it is, continue to move it, observe again, etc, until you move it over the item you want). A keyboard is on or off - :wq does exactly two things extremely quickly - three keystrokes and you’ve saved and exited from a text editor. You can do this faster than the time it takes to move your hand to the mouse, let alone begin to move it.
