SDL_JoyBallEvent ? and PS4 trackpad

I am curious, does anyone have a joystick/game controller that have balls? (no pun intended)
I never seen any controller with that feature or that identifies itself as having balls to SDL.

Since SDL_JOYBALLMOTION is already in the api and uses relative x and y coordinates, it may be useful to use it to expose the Dual Shock 4’s trackpad multi touch coordinates somehow.
