Hobie products have been up for consideration in the past. Typically, they are not accepted due to things like lack of build quality standards (significant boat weight differences etc) and durability. These are very important to the athletes and also to the selection committees. If the H16 is to have fighting shot, it must be tightened up significantly in build quality control and component design. This would create a disparity from the mainstream class boats, raise purchase prices and thus negatively affect one of the biggest advantages of the class..the low price point.
I don't know about all of that for the H16. It's already accepted for the Pan Am games, and has been used for the ISAF Youth Worlds.
The boat has gone through some continuous improvement through the years, which has been widely accepted by the class, especially as durability is improved. I don't know any H16 sailors that would have a problem with the improvements you mention (tightened weight ranges, etc.).
