Personally I'd vote in a heartbeat to prohibit panels behind door swings.
I've never liked closing the door in an electrical room knowing that someone coming in to 'help me work' (or pester me to work faster) would whack me into the panel that I was working on.
I've used the 'panic hardware' requirement for main electrical rooms quite a few times to get a safe working environment, but it's still a fight every time.
Without a Code item to hang our hats on the Architects will continue to make the doors to virtually all of our workspaces swing into the room, then whine that we should be able to use every square inch of space so that they don't have to make the CEO's office 6" smaller when they enlarge our room.
