        <pre>Update: our current plan for the physical buttons on the tablet is to add a
"buttonset" interface and the matching capability. To provide logical grouping
of devices, a tablet like the Intuos 5 Touch should have a single struct
libinput_device with the capabilities TOUCH, TABLET and BUTTONSET. This device
would be fed by three event nodes.

Because of how udev starts up and the path backend work the only sensible way
to avoid race conditions would be to add the capabilities as the other event
nodes appear. i.e. we need capability change events.

That buttonset interface is still WIP atm, but it does have a case for
capability events that's different to the touchpad case above.</pre>
