Yeah the guy in the article went farther than I would. I have a lot of connected switches but they are still functional as dumb switches. If you moved into my house they'd all work like normal, you might notice they didn't feel exactly the same as an old-fashioned switch but when you push up they go on, down they go off. I'd of course let the buyer know they had options to connect them, but they could just forget about that and go on with their life.
