I'd much rather wait until the other servers/minigames actually come out. A large amount of servers use /hub as their command to go to the main spawn and it might throw newer players off when they try /hub and it TPs them to the lobby, which currently serves no purpose, as opposed to actual spawn on the main economy servers.
Yeah let's wait until the hub is more than just the place we frantically hop and run around while builders freak about lost inventory when main server goes down for a few mins.
