Luis and I have pushed edits to the proposal that integrate most of @msa6867 's feedback and acknowledge @addison 's dissenting opinions.
Given that we’ve incorporated the feedback pertinent to refining the details of the proposed mechanism (stake-weighted rewards) and would be unable to incorporate the feedback that advocates instead for an alternate mechanism (stake-weighted session selection), we feel comfortable that this proposal is ready to go to voting.
I plan to put this proposal up for voting tomorrow. Note that voting will last 7 days (unless a 50% majority approves before the time is up) and discussions about the details of the proposal can still continue.
