Werner, we were using F21 in the past because we could not use evdev keycodes >= 248 (256 - 8 modifier keys) because of Xorg limitations. But recently the mapping of things like KEY_TOUCHPAD_TOGGLE / KEY_TOUCHPAD_ON / KEY_TOUCHPAD_OFF to F2x keys has been moved to xorg-x11-drv-libinput which gets the full range key-codes from libinput and can then do this mapping before passing the keys to the X-server. So it is no longer necessary to use KEY_F21 and even in the past we used to do the mapping in udev / hwdb rules not in the kernel in the kernel we've always (with a few exceptions which are my fault) used KEY_TOUCHPAD_TOGGLE as that is the correct keycode.
