Walking swings be it lateral or just regular walking swings are a good coordination drill. Swing step/swing step. It's not that hard, but adds a little variety.
Also, they make a good group drill for Workshops, Boot Camp type classes, or even just something to do outdoors to add variety.... .Do walking swings 20 feet, drop do pushups. Do walking swings 50 feet, do Sandbag thrusters, ect...Just a creative variation.
If you've got a field or a track you can do them for distance. I don't consider them complex if you've mastered the basic swing. Just a little coordination challenge and can be a butt kicker.
All that being said, I don't ever do them in my workouts and my workouts are very KB centric.
