Chicken/egg, I'd say. Do you want to land slow but short, or fast and long?
USE FLAPS 3 - SLATS AVAIL ONLY: engineers who designed the ABN PROC already understood that 2+0 would result. BTW the difference on approach speed compared to 2+3 seems to be 15 kts. Earl's contribution above gives all the answers I personally needed.
Even if on a short final (below 3000 ft with LG down) and looking good, the idea to tweak it with YEP and trailing edge flaps is not the smartest.
F2 from 0 have massively significant balloon effect and pitch down moment, while at that stage it is DCT law with NO MAN TRIM. Apart from handling the disturbance itself, lack of remaining elevator authority for the touchdown would be an issue.
Agreed on the controlled flare being what defines the survability.
