I think this may be useful for systemwide calibration data, otoh there may be cases where there are different calibration profiles and the compositor needs to give us the one which should be used. I think that having support for system-wide calibration data through udev directly in libinput is not necessarily bad, as long as we also have a config interface to allow the compositor to override the calibration matrix.
