Mastodon's lists replace the empty stubs: CRUD, members (only accounts the persona follows; a follow that ends takes its memberships with it), accounts/:id/lists, and timelines/list/:id from the persona's home entries with the replies policy (followed, list, none; self-replies and replies to the persona always). An exclusive list's members stay out of home. Lists never federate, and go with a deleted persona.
