that was my initial idea, but I guess we briefly talked about not 
ignoring any input device and this patch was an attempt to force someone 
more motivated later on building such support - I envision some client 
that will want to get data from accelerometer for gaming maybe and 
bypass the compositor & xkbcommon doesn't seem quite smart.
