Thank you for your suggestions.
Once SMT-lite arrives it will be also possible to implement most of this proposal on a non-concensus (non-native) level outside Steem, using SMT-lite as a native base.
I still need to modify the proposal to show how a non-concensus implementation would look, but nevertheless Steemit Inc. involvement is hardly necessary.
That seems like a good idea. I look forward to your modifications
