The advantage of using a closed-loop system is to compensate for potential errors, that means no more missed steps.
Cost reduction is not a goal, but we are trying to get this working within a similar cost range as steppers. This solution space has been explored, tested and discarded in the past for RepRap mostly because of its high cost. That is why I am so conscious about its potential cost.
You should get better linearity from a closed-loop position control than from a stepper.
