Sometimes you're in a game and you just want to requeue for whatever reason. For me, that's during speedruns when I may need to reset until I get a good seed. The current process for getting into a new world is very lengthy (/hub, potentially warp your party mates, go through the menu to requeue, wait to get placed in starting lobby, finally enter game)
It would be dope if you could just enter a command to requeue for whatever game mode you're in. Then ideally it would just drop you immediately into the next seed, or, bypass going to the main lobby and instead go to the waiting room lobby. Some may want to go to the starting lobby to change game settings, and others may want to just get dropped into the next seed whenever it's ready and bypass the ability to change game settings
