Yes. wsmouse handles attach/detach gracefully and hides the
communication errors, the X server doesn't see anything.

Yes, the hotplugging is handled by the wsmouse multiplexer (/dev/wsmouse)
but not by the individual instances of wsmouse (/dev/wsmouseX).

In my experience the X server tries to open the device and if that
fails, it simply ignores it. In case of the core pointer and absence
of the AllowMouseOpenFail option it doesn't even start.

However, the X server aborts when an input device that it had
open returns an error, e.g. when you unplug the mouse/tablet.
