As long as it will still retain the value of rotation count, it will be very useful. Otherwise, it will be bad! This will help in simulating an event driven instance. Do you see there is any down side of this implementation other than a few more (...) (17 years ago, 6-Aug-07, to lugnet.robotics.nxt)
