We think there will be plenty of utility for Steem-Engine tokens. Because they are centralized and use Soft/Emergent consensus, they can be modified more easily and updated more quickly because updates do not require a hardfork. This will likely enable that team to experiment with a lot more features. The features that have the highest demand would be perfect candidates for integration into SMTs. In this way Steem-Engine tokens could become a testbed for SMTs. There will always be opportunities to improve SMTs, but what we don't want to do is add features that have not already been validated by the market. Therefore, Steem-Engine could prove crucial in 1. offering valuable features to the market before they are available in SMTs, and 2. demonstrating the value of those features before precious engineering time is spent adding those features to SMTs. Hardforks are very difficult to execute and so any feature that does not HAVE to be in SMTs, shouldn't be. That should create ample opportunity for Steem-Engine tokens.
