The Message Wall page says: "Q: Will this feature be optional? A: Message Wall is scheduled to be in Labs in January. We will make more feature changes based on usage statistics and feedback before determining its next phase. "

And its talk page is now blocked from future posts, all those posting before that change complaining it was not optional.
