Agree 100%. On a slightly related note, the touchpad identifies itself as
"SynPS/2 Synaptics Touchpad," though I'm not 100% sure it's a synaptics

I foundnd the mouse moved ever so slightly when I touched or released the
pad -- so I changed the expected finger size:

xinput | grep 'SynPS/2' # to get the device id, should be 11
xinput list-props 11

# change "Synaptics Finger (271)"
xinput --set-prop 11 37 42 0 # 37=min size of a finger, 42=max size of a

# the previous value was: xinput --set-prop 11 25 30 0
