This is just a guess, but I'm guessing it's assuming the gear torque will keep it in place. From my understanding most of the servos are fairly simple - a small DC motor with a gearbox and control/feedback circuit. Adding an electrical brake seems like it would up the complexity quite a bit. Again, just a theory, don't blame me if I'm wrong!
