Personally I would love to see a suburb go completely rogue and draft up zoning laws that flipped the script and required their town be built to 1890's code.. or better yet, 15th century Europe code.

Victorian era density is nice but we have so few places in the USA that have any of the human-scale character of the Old World to pull from, that most Americans have no idea what a small walkable village really should feel like. If we want to talk about the good old days before postwar zoning in order to get the character in our places back, why not look at the places that are real gems that we never had at all, like UNESCO villages and such?
