I believe the spoiler is very important for what it can suggest. With Flaps 0, there is no airflow available to pop the spoiler out of its mounts. With any deployment, the area under the spoiler opens up and exposes the underside of the spoiler to some value of airflow. As with the Engines discussion (long in coming, I think), there is reason to entertain some configuration that at first blush might seem ridiculous, but perhaps not to pilots up against upset, uncontrollable a/c, and impact with the Ocean.
