I think you're looking at my post still too much from the perspective of D&D-like games.Yes, though they should also be able to turn the tide of battle and determine the outcome through thier actions and choices.
Apocalypse World (much more so than all other PtbA games I've seen) approaches scenes and conflict in a radically different way. All the things you pointed out are aspects already present in AW.
Though with it being a very unconventional game and this not being the topic here, I feel this is not the place for a full explanation of the system.
