@heluecht @evan delivering to an "instance" and expecting that the instance can infer who should get the message means that the delivering side isn't as in control of where the messages go, it violates the actor model, and precluded several possible directions for a more capability-oriented model which I think the fediverse should have pursued. I don't think "inferred recipients" is a good design. The poster (or more accurately, the addressed collection) knows best its recipient list.
