DLC in go around
You omitted the best thing about DLC.
If on approach with DLC and you need to initiate a Go Around, by advancing the throttles, the spoilers are sent back to zero from the 7 degree DLC nul position and you have an instant 1000 feet per minute rate of climb.
So while the engines are still winding up you are now over flying the runway obstruction in a calm cool collected manner, and not praying that the donks will wind up in time as on todays modern Busses and Boeings.
Clever chaps the guys at NASA-Ames who came up with the idea that Lockheed adopted so very well.
Could be done easily with the flying software of todays aircraft. Maybe on the B787????
