I am told the JT8D weighs 4 tonnes with cowlings and accessory gearbox, etc. That, along with the drag of a seized engine, make it a useful though unintentional jettison. Notwithstanding, it remains undisirable.
Any clever boys and girls got some ideas on the pro's of a 4 tonne instant jettison with gear stuck down (A hyd lost) vs a retracted gear, engine seizure scenario?
This aircraft is (thankfully not WAS) ex LH with smaller -15A engines. Sea level. Max pax with approx 10 tonnes fuel. Looks rainy (cool day), so assume max TO thrust. Bear in mind that with the engine (seized) remaining on scenario, the drag of the gear is still a factor in initial climbout until retracted.

Impressive flying display, in anyones eyes, well done
