Synaptics, Elantech and Alps semi-mt devices all have issues with reporting correct MT data, even the bounding box which semi-mt devices are supposed to report is wrong. Synaptics devices have massive jumps with two fingers down. Elantech devices may open slots without coordinate data. Alps devices may send 0/0 coordinates as initial slot position. All these may be addressable with specific quirks, but the actual benefit is largely restricted to better palm detection (though even with quirks this is unlikely to work) and support for pinch gestures (again, lack of coordinates makes supporting those hard anyway).
