Right now maybe, but Lemmy is open source, and anyone could fork it to add this functionality.
Yeah only per instance though, upvotes and downvotes are already public information so it wouldn’t take much for an instance admin to implement
If lemmy did this you’d see forks ripping this out, not to mention anything other than lemmy would not have it, so only a very small subset of the fediverse would be subject to this at all, making it perfectly useless
