There are a lot of use cases for it. Not common for average Joe but there are use cases in trails and other automated bots.

Lovely.
Did they set a new limit?

I haven’t checked the code if there is a limit. The reasoning behind the changr was less that it was needed and more that the limit was just some arbitrary rule that served no real purpose.

Uh huh, we'll see how long it takes to be abused.
I liked the 4 post soft cap on rewards, I don't see why I wouldn't like limiting voting to one per block, too.
But, it's done now, I guess.

What would they abuse, using all their voting power in a short period of time? So what?

I don't know, I'd have to think like an abuser.
I'd assume a bot net would be in play.
It does allow batching for trail votes, I guess.
How many votes can a block hold?
