There are quite a few cases of airliners coming home without an engine and 
the flight crew being unaware of its departure from the aircraft. Changes
in handling qualities are minor and are not the reason you would never
intentionally jettison an engine in flight.  The real reason is that there
is no requirement to do so and engines cost a lot of money.
