Isn't it equivalent to the one of filtering the geometry out? In one case the SQL filters the geometry out, in yours the geometry is returned as null and is filtered out by null checks in render code.
Andrea commented to check empty geometries on the render and I think it's the best since it would fix empty geometries coming from other sources, not only postgis. If no one has anything against, I'll try to produce a test case and a patch for that. Thanks!
