Why an extra switch? Most APs can be configured to turn off at a specific time. Possibly only after the last device has disconnected, you certainly put all phones in flight mode ;)
Yes, I know the feature but haven’t had good experiences with it. (PC restart, or you come home later in the evening, ...)
You might manage it differently, but in my opinion, it doesn’t look bad and works great. The position is also chosen so that the access point radiates perfectly into the room – but as you notice, the switch can be discussed.
