Thats what I also think, but the "only_first_person" and "only_record_player" things are a bit ... strange?
I added those with Wynncraft in mind. Wynncraft controls where the player can move / what they can see on may occasions (e.g. you may not climb over mountains or walk into certain caves) and the ReplayMod is not allowed because in the Replay Viewer you can just go wherever you want without getting teleported back.
I'm currently building plugins for Bukkit, Sponge and BungeeCord (
might also add LilyPad forget about that, that's not how LilyPad's supposed to be used, just use the Bukkit plugin for it). Due to the fact that server owners have to install an extra plugin to restrict the mod they for one have to know of its existence and also have to have a reason that makes it worth to install an additional plugin.
You can currently divide servers into two groups: Those that allow the mod and those that ban it completely. With the plugins the second group is split into banning it completely and restricting it's functionality, the first group of servers stays the same because they have no reason to install one of the plugins.
