Maybe it would if Rockstar got their heads out of their asses and actually supported the community with proper tools. Instead of just making use of iCEnhancer for GTA IV when making an in-game film.
Actually thinking about, following the whole hot coffee incident and the consistent usage of GTA as a scape goat for anything disturbing in video game land, I doubt they will ever officially support mods. They probably don't want any association with the disturbing / polarising mods being legally associated with the company or something they are responsible for
