I think you are missing a silver lining. We knew that they had the code for things that were toggable at the player level (i.e. auto-gold pickup). Now, we know that they have the code
1.for a game creator to set the identity of the game that they create
2. a filter system for others to find it in multiplayer that is sophisticated that takes into account the achievements of all players that opt in.
We have talked alot about other toggable options. Blizzard still need the code but it means that the setting the toggable at game creation and filtering games for opt in is solved.
I am secretly or not so secretly smiling.
