I would hope that by now all hardware like wheel mice, dial boxes,
tablets etc. all use XInput and device extensions.
Last I messed with Xt I encountered this when writing a small program
to use a Wacom tablet from Irix 5.3:

I included the source which shows how to access X extensions,
rare to come across at that time (1998). I recall Linux was just
jumping onto the XInput stuff too, so I would hope by now that's
been standardized.
It certainly looked clear that was the direction things were going in
the X world. It's certainly the direction Wacom went for pen
pressure/orientation/etc in their device drivers.
Would like to think Sun went that route too, not sure.
