EntityTeleportEvent has no way to tell which dimension target will be teleported to

[3TUSK]

Suppose that I marked a "restricted area" and disallowed anyone to entering this area by any means. Which means I do not want players to teleport into this area. Consider the following snippet:

@SubscribeEvent(priority = EventPriority.HIGHEST)
public static void onTeleport(EntityTeleportEvent event) {
    var targetBlockPos = BlockPos.containing(event.getTargetX(), event.getTargetY(), event.getTargetZ());
    if (/* Teleport target is in the restricted area*/) {
        event.setCanceled(true);
        actor.sendSystemMessage(Component.literal("Refuse to teleport you into restricted area"));
    }
}

The above code should work for the said purpose. However, I can see at least two cases where it won't work well:

• The said area is in The Nether; a player attempts to /execute in minecraft:nether run tp @p <x> <y> <z> from overworld.
• The said area is in The Nether, and (conveniently) there is a nether portal nearby; a player attempts to trespass the restricted area by throwing an Ender Pearl through the portal

For case 2, I understand that I can specifically subscribe to EntityTeleportEvent$EnderPearl, and retrieve the correct dimension via pearlEntity. For case 1, however - I do not have any information about which dimension I am being teleported to.

Would it be possible to either

• Have a "target dimension" in EntityTeleportEvent, or
• Provide extra context in EntityTeleportEvent$TeleportCommand?
