The for and against convention is a good idea, though I don't think a set "result" date is really needed. The purpose is really to get a 'sense' of stakeholder sentiment and that changes over time too. Even if the 'result date' says one thing, by the time a fork got implemented, deployed and was ready to activate, stakeholder consensus could be different. IMO, if the balance of sentiment is so close that it requires a careful rule to determine the winner, there is no real consensus either way and it probably makes sense to continue working to try to build one.

Yeah I agree with some of the comments about SPS not being an ideal polling system, but it is the best we have and creating something only a little bit better would be a lot of work for a small payoff. It would also risk having even lower participaton by splitting up attention into more and more separate voting systems.
