I am kind of afraid that if voting becomes more public than it already is, it will lead exactly to more of the kind of "zero-content downvote" accounts mentioned in the ticket. Because some people are just wildly irrational when it comes to touchy subjects, and aint nobody got time to spend an eternity with them dismantling their beliefs so they understand the nuance you see that they don't (If they even let you). So it kind of incentivizes people to create an account like that to ensure a crazy person doesn't latch on to the account you're trying to have normal discussions with.
But I understand that they can technically already do this if they wanted to. So perhaps it will be fine as long as we fight against vote viewing being weaponized as a community.
