Yup. Hazards are live all the time. Think of it. You are broken down and need to use the flashers. Then need to walk to find help. You want your keys with you while the flashers continue to warn other drivers of the dead vehicle.
Of course this doesn't work when the battery or its wiring fails. Happened to my wife on a busily travelled 4- lane road at night, in the rain. The battery terminal fell off the battery and the car just died. (not the wire clamp. The actual battery terminal!) No flashers at all.
