I doubt it; AMD just released these files, and even if Valve did have access to them for testing, they wouldn't have rolled them out yet.

A few things:

• Several of your devices have the feature you want, but you ignore or defeat them because you want another feature as well (play next episode, etc)
• You could look into Google Home Automations, on your Android phone, where you set a specific time, 00:30, to automatically turn off the CCwGTV.
• Last, this is one area where home audio / video (AV) receivers help; just connect everything to the AV receiver and when it goes off, due to its sleep timer, everything else goes with it. Likewise, when you turn on the AV receiver, everything else plugged in turns on.
