The PointerEvent interface provides explicit support for touch, pen
devices, and it inherits support for mouse input.  I agree that all
sources of "pointer" input are likely to have some attributes in common
with PointerEvent and one can always compatibly add more by extending the
interface further. You could similarly justify the same claim about
MouseEvent and in fact that's the role the existing mouse input system has
played in this spec. In my opinion, suggesting that a new API will be
compatible with or extensible to all pointer input hardware from now
forward, overstates what's practically possible or even useful.
