do you want to enable/disable based on modifiers too?
only modifiers, but combos as well (ctrl+c, ctrl+v)?
do you want to only disable tapping/scrolling, but not movement?

seriously, the options will just pile up, requiring configuration, etc. and
the last thing we need is more config options and properties. we've got
something that's working now. not ideal, but well enough. afaiui the biggest
issue is the costly monitoring of keyboard input by the client, not the
single request to enable/disable the device.
