I guess one reason why no one is paying attention to it is because is the Wi-Fi speed usually the limiting factor?

On a LAN? Pretty easily if you have a gigabit or greater network. Wi-Fi 6 can do close to gigabit but not consistently and needs to be close to an AP, and it’s unlikely a bunch of devices using it at the same time will be able to do maintain that peak. Maybe 6E, although I don’t have any devices myself that support it.

And WAN speeds of gigabit and greater have become more common, too.

And this ignores the improvements in latency with Wi-Fi 7, which is definitely an issue with traditional Wi-Fi.
