I'm assuming that density can also be a concern here. I definitely have places that I would not want to turn off 2.4 due to poor coverage - i.e. 2.4 has better range that I need in some places and I have so many places to monitor that it would be difficult to see where I could turn it off. If there's an easy-ish way to tell where I don't need 2.4, please let me know.
