Touchpad KCM on X11

xf86-input-libinput driver is installed and xf86-input-synaptics driver is not installed on my desktop computer running Arch Linux but I see the old Touchpad KCM in system settings when running X11 session anyway.
On Wayland session I see the libinput Touchpad KCM as expected.
Compare the attached screenshots please.


STEPS TO REPRODUCE
1. use a desktop computer without a touchpad device and make sure synaptics touchpad driver is not installed
2. open system settings > input devices > touchpad on X11 session
3. open system settings > input devices > touchpad on X11 session on Wayland sesison

EXPECTED RESULT
libinput Touchpad kcm should always be present in system settings when synaptics touchpad driver is not installed.
