It’s too risky to make a big code change to remove SBD in the next SMT HF, so we are at least a year away from being able to shed SBD if we wanted to so we may as well try fix it in the meantime. Also stablecoins have been a strong narrative in the 2019 crypto space with the advent of DeFi, multicollateral DAI etc and would be a great complement to an SMT token economy so it is worth fixing and eventually get a smartcontract managing SBD and other steem backed stablecoins at blockchain level.
