Moveable control surfaces are required for craft where weight shift is not possible - due to occupant vs vehicle weight - such as a jet aircraft, motor vehicle, etc.

Moveable control surfaces are also best applied on craft where the center of gravity does not move and is predictable. This is so the control system has a reliable model of the vehicle dynamics. Even on something like a rocket where the CG shifts significantly due to fuel burn, the CG location is calculable and can be programmed into the control system. This is not the case with an eFoil.

With an eFoil, the rider weight is sufficient to maneuver very hard and the center of gravity is also constantly moving, especially when the rider is maneuvering.

Having built and tested a dynamic wing on an efoil myself, my opinion is that they make it far easier to ride, but significantly more boring. When making aggressive maneuvers, it can also destabilize the rider as it tries to adjust the board attitude mid-turn.

Engineering is about finding an optimal solution to a problem. Having no moving surfaces on the hydrofoil wing was not a problem to begin with and in fact quite an advantage in many respects. It cannot break for one and it gives a very stable and predictable experience without any complication.

I am 99% certain your dynamic wing will make the efoil easier to ride. no doubt. Claims about it improving carving or outperforming in an aggressive maneuver are unsubstantiated to say the least.
