@nyx @kallisti It is such a pain to debug and Masto's code is nigh-unreadable. I spent an entire day trying to get signatures correct because the documentation does not match the behavior. I can only imagine what new horrors await me the more I try to add.

LitePub was essentially Pleroma forking the spec because ActivityPub authors were ignoring everything that wasn't Mastodon. The prospect of forking the network made them reconsider and they started working with Pleroma's dev team, so fleshing out LitePub became a lower priority, but lanodan said if there's interest in it, then it might get picked back up.
