I answered too fast... Later in the thread John offers
waterway=spillway + emergency=yes + surface=* which seem even better
because it uses the generic emergency=yes instead of creating a new
spillway=emergency

spillway=* would only become preferable if a taxonomy of spillways
exists (such as main, secondary, emergency etc.)
