that's how is expected by Xorg.

Yes. As soon as you attach a tablet, it is automatically added to
wsmux0 again. We need some kind of automatic or at least manual
policy to decide which "mouse-like" devices should attach to wsmux0.
For example an ioctl setting or sysctl that allows for:
1 - attach all devices
2 - exclude WSMOUSE_TYPE_TPANEL like Xorg
3 - if there is a mouse, only attach other mice.
4 - ...
N.B. Keyboards have a similar problem as the multiplexed keyboards
can only have one common keymap.
