> Is follower-only a thing on ActivityPub?
Yes. They're called Followers posts in Mastodon now.

Yes. There's been all sorts of research into things like Object Capabilities, that could force receiving servers to do what they're told. But for now, not displaying Specific People posts publicly, or showing Followers(-only) posts only to followers, is an unenforceable handshake agreement.
