It's all speculation till a rep/dev comes in and says something. If it's just an emote then why not let them filter it? Even if it can be used to traverse the terrain... who cares? If they want to see people sliding up and down cliffs let them. If it's not doable then they can deal with it, but in the end that's a call the devs will make.

I'm pro jump, that's my opinion, but I don't really care if a filter is put in place for those who hate it. It's a fair compromise. It doesn't ruin my ability to jump / see other people jump so why should I give a crap if someone else can't see it.
