There is almost unanimous consensus between the top 20 witnesses but, at the same time, we recognize many do not want to see their inflated author rewards to go away. For the most part, it seems witnesses are not willing to implement a reverse conversion unless the price drops closer to $1. We don't want to be the "bad guys" who turned off the SBD faucet, even if we're thinking about the long-term benefits of the entire ecosystem (including increases author rewards due to increased value of STEEM and the resulting rewards pool). At this point, unless more people demand action from the witnesses, I don't know that much will be done.
