I'm beginning to come to that conclusion too.  

/usr/xsrc/xc/programs/Xserver/hw/xfree86/common/xf86_Mouse.c does
extract the Z-axis information from the wsmouse device, but then
essentially discards everything but the direction of motion.

There is another X11 input device, a tablet which does manage to pass
3-extra axis of information to the client (pressure, x-tilt, y-tilt).
I may try hacking my local copy of the xfree code to put the mouse's
z-axis into the "pressure" slot and calling the tablet output code.

I'm very surprised that nobody has done anything like this yet.
