Give me a break Wouter, everything is not about you.....
The level of competition in A-class is a higher than in F16-class which means that small changes in the performance of the boat makes big changes in the racing results. That's not the case in F16 right now but it could change and I bet that those sailors at the F16 worlds also would like a bit stricter rules so they can focus on sailing.
The international canoe is an example of a class that is divided in three types of boats now with different rules. IC (the original), AC (added a spi) and DC (development). The last worlds had 21 IC, 3 AC and 13 DC but they could have had 37 boats racing together.
