Never gonna happen. People (including myself, often) have been complaining about this sort of thing forever. Like random outfit changes. I have 6 mods with lines and lines of tuning I've modified to fight this kind of behavior, and every game more of it shows up. I even made a guy called Maxis Max who lives in my town, wearing every possible accessory and silly clothes item I could pile on as a loving tribute. It's just another reason I also made mods to keep random townies to a minimum (or not at all).
BTW, one place you can really see this is on warm and cold weather outfits for pre-made sims that come in the game (the ones who come in packs from before Seasons). Instead of taking the time and going in and permanently adding those outfits in a way that makes sense, they are randomly generated every new game. So families like the Goths wear something stupid, and tend to sport nose rings and glasses even if they don't normally do so.
