There are implications to the protocol though, for example you and I can communicate despite being registered to different parts of the fediverse. The lack of any safeguards against a group being unruly in ways that affect the rest of the fediverse (Lemmygrad comes to mind) seems like something that would backfire, kind of like if I was queen of a territory but then joined the US as a state and then proceeded to send people to the three branches of government just to troll the system. But there are safeguards against that, just not on Lemmy.
