IIRC, at the time, the problem was that nobody had the hardware and the implementation was solely based on the specification only. I didn't want it to go in without any actual testing, so it was put on hold for the time being. Do you have access to a device with zsero power support? If so, are you willing to test the implementation? Hmmm... at the same time, I'm a little bit doubtful about its usefulness. How much power does it save? Furthermore, ODDs are often omitted on mobile devices these days. So, I have a slight reluctance against including it but if the implementation is clean enough and there is enough benefits it shouldn't be too difficult to overcome.
