What about the top speed limitation? That's going to be impossible to
enforce. It will split between underpowered airplanes, and people who
lie. It would have been so much simpler if they had just stuck to a
max wing loading spec. (not that you'll have a problem with the top
speed, but many, like the Sonex, will)

Here's the Sonex info. Looks like it will do just fine:
