In a multiplayer game, when the last seat is filled, the page changes to one that shows each player and a "Cancel Game" button.
At this point, if the game host sees that (s)he doesn't want to play with one of the players -- eg, the player has a bad reputation or is on the same ISP as a second player and is likely cheating -- the only option for the game host is to cancel the game and start all over again.
If the page didn't change, if it remained at the sign in page, the game host could simply eject the unwanted player.
Please make this so.
