Hrm... I don't have very many "interesting" keys to test, but when I hit
the menu key, I see KEY_COMPOSE, which is > KEY_MIN_INTERESTING.  When I
press the button to have my vnc client send a windows key, I see
KEY_LEFTCTRL+KEY_ESC.  I also see KEY_PAUSE when I hit that key and it
is also "interesting".  I get the same thing with or without this patch,
so it does not appear to be breaking delivery of the keys that are no
longer being advertised.

Oddly though, libinput list-devices does not even show the Xen Virtual
Keyboard.  It's sysfs path is /sys/class/input/input1, but it also does
not have a device node in /dev/input so I can't even ask libinput to
only monitor that device.

Ok... this is really odd.. it does show the device without this patch,
and not with it.  The input events I was seeing were coming through the
"AT Translated Set 2 keyboard" and no events come though the Xen Virtual
Keyboard ( even without this patch ).  This makes me wonder why we have
this device at all?
