I wouldn't say decentralized, but strictly talking, to add a new pool is a contribution to widen te distribution of hashrate (as long as they are succsesful recruiting miners), the most interesting to see from my pow is what they call phase 2. All the rest looks quite similar, like payment thresholds, custody while it is achieved (an escrow would have been nicer)> It's going to be interesting to see how they evolve, but a new pool with different model is always good
