I think that the Sims devs are friendly to the idea of having occults in the game. They made the best vampires we've ever had. I'd say that the issue is more that the "realism" crowd is over-represented among the Game Changers, and that those Game Changers in turn really have the ear of the dev team. Some of them are outright hostile to the idea of having occult life states in the game.
I put "realism" in quotes because that aversion to occults also extends to elements that present more negative outcomes for sims -- things like death types, debuffs, and generally other things that can make sims miserable. Those things are also part of a realistic experience, but they get in the way of the playstyle where one's perfect supermodel sims live their perfect nuclear family lives with their perfect children. It's fine if that's how one wants to play The Sims 4, but it shouldn't be the only way to play it. It's why vampires don't visit anymore. It's why the weirder content get partitioned off into dark little corners, and it makes me wonder if there will even be occult lifestates in a hypothetical Sims 5.
