Currently there is only a definition for long press, so this API isn't all
that useful. (This is also why the preference is hidden away in SpareParts,
it's not really ready for prime time.) If you are giving feedback for a
long press, then you may want to use it... but if you also feel the need to
have it ignore the preference, then please consider having your own
preference in your app since some users really dislike this stuff.
