Is the assumption on which FEP-fe34 is based valid? Of course, it is primarily a philosophical question. Who should be responsible for enforcing boundaries between actors hosted on the same server, the sender or the recipient? In my opinion, the answer is clear: the sender should be responsible. As far as I know, the majority of existing implementations do enforce boundaries between actors. I am not aware of any implementation that doesn't do that. Enforcement of boundaries is challenge for generic ActivityPub servers, but it's not insurmountable.
