Using permissions.json doesn't really help here. I'd like to leave my server open to anyone (no whitelist), but not allow them to break anything. So, I need a way to set the "default" permission to visitor, which is what the default-player-permission-level setting is supposed to do. Unfortunately, it doesn't work, so all visitors are granted member permissions, which forces me to restrict access using a whitelist.
