I propose and have for a very long time that we ADD the downvote to the other two. Witnesses rarely change because it's easier to get to the magic number when the smaller stakes have no rebuttal to the larger ones.
By adding the downvote to proposals and witness elections, we the people could actually override the largest stake holders who keep the status quo as is and the community can be in control, rather than the Oligarchy.
I suggest, like I did, for others to create a proposal for this. I appreciate your input and energy to this community focused proposal!
