Body hair and pronouns were the only two things on the list that actually feel like "causes" to me, because they're important for making sims the way people want them to be. And as a non-fan (don't hate it, just don't love it) of body hair, I'd rather have pronouns, even if I think that's the more difficult one to implement due to some languages not having suitable options.
I mean, yes, I want more occults - especially werewolves. Yes, I want cars, and yes, I want hotels. But those aren't "causes" They're wants, and in the case of hotels and occults, probably not even particularly difficult ones. They just need to find the right secondary themes and work them into the schedule.
As for the rest... There are a couple that I think are already in the works, so making them the community "demand" I think would be detrimental if they decide to rush something out (see: Bunk Beds released in a workable, but not quite finished state.) There are others where I don't think people realize the complexity of what they're asking for, so it may be a while even if they are working on it.
