On Wayland we don't need the Touchpad KCM init on startup anymore. But since it still executes the code and then branches in NOOP, all objects are created anyway. This means, we waste memory and there are useless debug lines in the log.
Therefore try to make the init on X not necessary anymore, either by replacing or (as soon as Wayland session can be considered default) removing functionality from the X version of the Touchpad KCM.
