Wireless is super overrated IMO. Adds a lot of physical/electrical complexity (now you need batteries, some battery charging electronics, the wireless controllers themselves, ...), increases latency, and makes the programming a whole lot more complicated (meaning you get stuck with whatever firmware someone makes for it, because the 3 alternative open source keyboard firmware implementations aren’t going to bother implementing stuff for one specific board, and meaning if you decide you want to fiddle with the firmware yourself you now have a lot of extra complexity to wade though), requires a bunch of extra UI to figure out how to match the keyboard sections up that you care about, configure how they’ll work, and decide what to do when one or more parts goes offline, etc., for pretty marginal benefits. Then you need to consider whether anyone with an antenna nearby can listen in on your keystrokes; to do this properly you probably need to encrypt everything, yet another layer of complexity.
Overall, wireless makes everything more expensive and less hobbyist friendly.
