Just wanted to potentially bring this up as an idea, whether it gets seen or not. i don think it'd be a bad idea to be able to ban/set trust level for use of pets on your island. Some pets, like the bat pet for instance can be used to gain access to parts of your island that people wouldn't normally have access to unless granted it by the owner of the ob. Even if this were not to be added specifically as it's own setting in the /ob settings ui. Maybe you could make the bat pet's flying capabilities link with either /fly perms, or maybe even elytra perms specific to your island.
