yes indeed. If it is implemented as proposed, there will definitely be communities built around SMT, even already existing communities will cash in on the opportunity not to talk of steem blockchained powered projects like busy.org, Dlive, esteem, etc.
Creating room for diversification of interests and unique financial instruments built around the basic uniqueness of the steem blockchain is something that should be pursued and implemented as soon as possible. There is so much to be gained.
