contact geometry definition improvement suggestion

According to, the contact geometry of a PointerEvent is represented only as a { width, height } which implies a geometry that can only be an axis-aligned rectangle (or ellipse I suppose).  What about hardware which supports more accurate contact geometry information?  For example, with the current specification, I cannot easily tell if a user puts a finger on the screen and then rotates the finger, even though my hardware supplies this information. Can more information be added to more fully specify the contact area?  At a minimum, adding a rotation angle would allow for the geometry to not be aligned with the screen.
