the rtp command can be abused in an unintended way to easily find worldgen features such as structures. it's so mostly because it can be reused infinitely to find ungenerated chunks. what if that wasn't the case and the command could be used only once?
making the cooldown infinite would force the player to use the command only once and never again. this makes this a perfect way to escape a server's spawn without giving yourself too much power over the world.it's a solution i'd love to see within your mod!
