Dust votes are fully considered as votes (it will no longer be possible to delete a comment that has received dust votes)

There's this certain comment I made more than seven days ago that I'm trying to delete but was unable to no matter how many times try despite getting no response and no upvote/downvote dust or whatever. Is this a bug thing or a feature?

Eliminated rule that prevented voting more than once per block (only allowed one vote every 3s). Vote edits are no longer penalized with no curation rewards - they behave mostly as if the original/previous vote was not there

This probably sounds like a stupid question. Is this final and executory or will there be necessary witness consensus for this to get implemented globally?
