It's very tedious to have to manually swap out a client-side mod in a modpack (e.g. GTNH) to either get to see other players and mobs on a server, or to comply with a server policy of not getting that. Architecturally, it would make much more sense to me for this to be a server-side setting--have a config file that determines whether players connecting to the server get the "unlimited" or "fairplay" experience.
