This is true. There is no doubt that the models become more sensitive to the elevator as the balance point is shifted back within the allowed range. But that's easily dealt with by altering the control linkage to reduce the total elevator throw. The model will respond similarly to before if this is done right. But the sensitivity to speed changes from throttle or gusts is reduced by a lot.
