Bring back landscape mode for AOD. I want to be able to use my phone as a "Desk clock" while charging at night. I would say for a majority of us, our phone is also our alarm clock. Please allow the AOD to rotate to landscape again! 
Iphones have "standby" mode to do exactly this, showing a clock and calander. I would be happy if you just allowed landcape back. There's no need to reinvent the wheel.
A simple toggle for Portrait/Landscape/Auto should satisfy all. You could also add randomly changing position of the display to ease those worried about burn in.
Simple is great
