So why is it that a youth boat must have a spinnaker?

The Hobie 16 makes a terrific youth boat - there are tons of them available and active. Practice and competition can be had on every lake and ocean. I don't see why we have to bastardize it by adding a spinnaker to a platform that was never designed for it (and a class that won't support it). Are we afraid that the kids might get bored with a main and jib? Let's not get too confused here - there are a few of us (and the bureaucracy) that gets bored with main and jib but even then, there is light years of information we would have to obtain to master sailing a 'simple' boat like the H16.
