Especially since DS, 3DS and Wii U gamepad had resistive screens. They could use a thin bit of plastic as a stylus and you could get very precise instantly with it.
Capacitive is nowhere near as convenient for (most) game interfaces. Fingers are inaccurate as fuck and get in the way of the screen, big round styluses are only marginally better, and even those clear-disc capacitive stylus things don’t work as well and are still usually quite a bit thicker than the DS bit of plastic.
With the Switch screen being capacitive too, I’ve tried using a capacitive stylus to design Super Mario Maker courses. It’s just not the same, it was a lot easier on the Wii U screen. On the Switch I have to go back and correct stuff constantly, and pointing in particular doesn’t always register immediately.
