If anyone is curious of why this could be useful, this can be utilized by clients for an in-game ready system and allow any toggling to update UI in real-time for all other players connected. Can also be used to see in-game of any other players who have completed their goal without needing to explicitly listen for Goal PrintJSON, which requires players to be connected to even listen for it anyway.
