Well, for my own nefarious purposes, I would’ve preferred to have all the info in one place. I’m not using Lemmy or Mastodon, just messing around with ActivityPub, so it’s be easier not to have to rely on past data about who voted for what that I haven’t necessarily kept.
For anyone else wondering, btw, it’s because lemmy expects all ‘id’ fields to be unique, so it would error if the inner object actually was a copy of the original vote.
