The only real downside is if you are like me and do not like the exponential function.

At the time that Jim employed the diamond shaped stab airfoil, contemporary servos were not that great at recentering. Fuzzy trimming around neutral on the elevator was acceptable, maybe even desired by some pilots, hence the diamond airfoiled horizontal stabs popularity for a while.

Today, our servos (and control linkage set ups) are much more precise. I would rather be able to choose the amount of "fuzziness" myself via the electronic adjustment capability of my transmitter, or even that available with some digital servos than to be saddled by the arbitrary amount that was imposed by the mechanical system of the airfoil shape.
