But mostly I think that we should regulate spinnakers as to avoid owners going off in all directions which will be difficult to reverse at a later time.

It has also been my experiece on the Hobie Dragoon that such small spinnakers are very easy to handle and don't require much hardware. For example a 7.0 sq. mtr spinnaker won't have to use ratchetblocks and can get by with really cheap simple blocks.
