...It's borderline possible that a system dedicated to dodging incoming fire might be worth the while.
But maneuverability doesn't do that - we have seen starships turn on a dime three times over, and still the hit rate in the TNG era is 100%. It would have to be some sort of ECM, and that doesn't much affect death rays. (Okay, a tractor beam affected death rays in "Way of the Warrior", probably both shaking the firing ship and, if the visuals are to be trusted, slightly diluting the death ray itself. But that's unlikely to be applicable often, and in any case it was only ever tried because the heroes couldn't have shields.)
Would anti-projectile ECM be useful? For all we know, what we see is already proof positive that it would not. After all, torpedoes do find their targets - and we have no a priori reason to think this would be because there is no ECM. It's quite likely that torpedoes simply are immune to it at the time and age depicted.
