You have forgotten the versatility of the F16 class unlike the T's and B Class, not all sailors want to sail with the rockstars, not everyone wants to sail always with a crew, an awful lot though want to be able to launch a light weight cat either as a single hander or with a crew and compete at the front, at their local club race.

The boat that would pose a problem to the F16 class would be if a fully compliant boat became the Olympic boat and some of the new designs such as the Falcon and Raptor are good enough for that role.
