I flew CEB-MNL on a Philippine Airlines 747-400 and deplaned via stairs. This is common practice there. Since PAL uses their 747's for the long international flights later at night, they don't pull into the domestic gate at all. Instead, it stops short of the gate to deplane and then the workers ready the plane for the international night flight and "drive" the plane to the international terminal.
BTW, a bus took us to the terminal. But while waiting for the bus, I stood next to its massive engines and got a fresh whiff of jet fuel smell. Awesome!
Its better to be on the ground wishing you were in the air than be in the air wishing you were on the ground. Fly safe!
