Android 6.0.1 'Do not disturb until next alarm' feature disappears

Do not disturb until next alarm returned with Android 6.0.1, but is gone again
This is the second time that the powers-that-be at Google have eliminated this option. The first time was with the Android 6.0 update. The reason that it is needed at all has to do with the way that Android mutes a phone. Instead of simply turning the volume slider down to "0," Android offers three different settings. You can choose to receive all notifications, only notifications with a priority tag (including alarms), and no notifications at all. The "Do not disturb until next alarm" feature allows pre-set alarms to go off even with notifications silenced. Once the alarm rings, the notifications are automatically turned back on.
Does Google have a secret self-destruct timer on other Android 6.0.1 features?
