I definitely want season cycle control and greenhouses. I'd also want more harsh weather options/improvements and holiday improvements, so yes to hail, fog, blizzards, and more, too. I'm neutral to compost.
I draw the line at lawn maintenance, though. I've not complained too much about any of the chores thus far (laundry, vacuuming, etc.), but I do not want major annoyances added to my game retroactively. I could theoretically tolerate pool maintenance depending on how laborious it ends up, but having to maintain what is currently terrain paint is too much for me to not be able to reject it.
