The older #XboxLive #MPSD API has been deprecated last year, and new titles need an exception in order to be allowed to launch with it.
And I am definitely not tooting about this because we learned about this deprecation only now, and have been using MPSD in a game that we would like to get certified soon. Nope, definitely didn't happen.
(In our defense: The documentation doesn't mention it anywhere. Just an obscure login-only forum post does: https://forums.xboxlive.com/articles/152939/upcoming-deprecation-of-multiplayer-session-direct.html)
