To an extent they do, actually. First of all, every elite level lifter built their strength by putting on muscle, which is how they arrived at their current weight. And let's not forget that many competitive lifters below the super heavyweight division cut to make weight. The goal is to come in at the very top of the weight class. Look at Matt Kroc. He certainly trains and eats for size, but the guy regular cuts something like 30lbs to make weight prior to weigh-in. And look at just about any lifter who competes at an elite level in the lower weight classes (anything beneath superheavy, really) -- what do they all have in common? Most are incredibly lean. They make a certain weight cutoff through low body fat %, not by limiting muscle gain. It makes no sense, whatsoever, to try and stay in a weight class by limiting lean mass gains. Frankly, if you have to actively eat in such a way to limit muscle growth in order to stay in a certain weight class, then you're probably in the wrong weight class to begin with. Everyone has a "natural" weight class at which they have the most potential for strength -- much of it having to do with height. So if you are 6'2," don't think you are ever going to be truly strong remaining under 200 lbs (or even 220), it just ain't gonna happen. You can have the most efficient CNS in the world but without "filling out your frame," you simply won't reach your potential. If you are a tall, lanky kid getting into o-lifting, you don't try and stay in the 77kg class by training for CNS efficiency and eating like a pigeon... you bust your ass in the gym and eat to put on size until you build enough muscle to be competitive in a higher weight class. CNS efficiency can only take you so far; ultimately, your strength will be limited by muscle mass.
[edit] I forgot to add, why do you think there are weight classes in o-lifting and powerlifitng in the first place? If CNS efficiency were sufficient, we wouldn't see such a huge disparity in lifting totals between weight classes. The 105kg class will always poses higher totals than the 77kg class ... why? Muscle mass.
