Nobody designs a passenger aircraft that way, but certification costs for a new design can drive them to keep on stretching. The basic 737 fuselage has grown more than 10m from the -100 to the -max8.

If a pilot were to always fly within the aircrafts flight envelope, never botched a take off or landing and was never shot down, a fighter would not need an ejection seat.

Transport class aircraft don't have ejection seats.
Neither for crew nor for selfloading payload.

Civilian air craft except for possibly aerobatic aircraft are designed to be inherently stable because they don't need to be as maneuverable as a fighter. The design intent with civilian aircraft is that if it is trimmed correctly, when you let go off the controls it will return to straight and level flight.
