Interesting idea on making proposals quiet until the proposal lead generates enough Yes support to open the proposal to everyone. I suppose that would advantage whales who can quickly generate that threshold of support, but maybe it’s worth flushing out further.
I think it is a hard sell to convince people to not vote for something if that results in lower voting rewards for them compared to voting for it. Hence, I would avoid taking this idea in that direction.
It’s hard for me to tell because there are so many ideas people have presented with a lot of comments, but it is possible that someone is working on something along these lines.
