No, it is not a red herring. Acceleration is the rate of change in velocity and this has a direct impact on the amplitude of the wave generated.
If I have a driver that moves 1mm in 1 millisecond vs. the same driver that moves 1mm in 10 microseconds, which one do you think will have the higher amplitude? The force of compression of air is much greater with traveling the same distance in a much shorter time frame.
A larger surface area will also give a higher sensitivity for a given force as clearly more air is being moved. A large e-stat panel will therefore be able to make a reasonable SPL level without having a particularly strong motor and therefore somewhat slower acceleration.
You can make ribbon speakers with high sensitivity as well...but it takes very powerful magnets to do so to generate the acceleration needed for high sensitivity. Again, back to acceleration.
