it also doesn't provide stuff like isOnline() (you had to have a Server reference to get an OfflinePlayer anyway, just ask the Server if the player is online ...) and getPlayer().
these methods have better pathways through Server directly.
Also, setBanned() does not allow customising the reason for banning or the duration, nor does isBanned() account for IP bans because the code is so old ... better to force dependence on a central code path to avoid these inconsistencies.
I want to do the same thing for OP, but that's a separate problem due to its effects on the permission system.
