I doubt they'd be changed drastically because it's part of the stock game, so to remove access to it completely would break the trophies/achievements for anyone that doesn't have it, especially new players. I'm sure the conditions are the same, but tracking them will be slightly harder (or easier if they realised this is actually a problem) because doing a different activity will earn you marks anyway. Pretty much you just do what needs to be done for either one and you'll get it sooner or later, is my guess. I don't have Notorious so I'll test it out that week since I don't particularly care about getting the platinum trophy.
