I also have a question.  I understand that SuperNET allows users to use features of different coins, presumably coins with the best current tech.  So let's say BBR currently has the best anon tech, but what if in the future a new coin comes out with something better and joins SuperNET.  What would happen to BBR?  Would anyone have an incentive to continue using BBR's older anon tech?  Likewise, would BBR still have an incentive to continue being in SuperNET if no one uses their anon tech?  And this goes for every other feature out there too, not just anon sending.
