Can’t read the article, but based on your list, one they missed was the second story overhang with openings on the bottom so you can shoot down on hostiles trying to get into your house.

I live in a 1913 farmhouse remodeled in the 50s. I have a boiler with hot water heat in the walls and a sunken full-room pantry with a window that can open for bringing in cold air.

My most popular feature, though, is the big pocket window in one of the bedrooms.
