libinput's click method setting is not exposed by the driver. To enable clickfinger behavior for my non-Apple touchpad, I had to patch the Apple check out of libinput.

Patches work well, providing method selecting both via option and via properties. However, when option is set to "clickfinger", list-props still reports "buttonareas" being enabled even though it's really clickfinger. Setting the property matches up behavior and property, though.
