Is this now standard procedure?
Having had two engine flameouts at altitude I can tell you it's a very benign event. You get some yaw but nothing like a engine loss at V1. The aircraft decelerates slowly and that rate decreases after selecting Max continuous power on the other engine. You have plenty of time to call ATC and get a clearance to descend before the aircraft reaches clean speed. There is no need for a off airway turn unless directed by ATC.
