I’ll definitely implement it on a button press in by AppDaemon linked to the Home assistant.
Now if it could work on non apple devices (like when pressing the button on your router) I'd certainly code something with it too!
Usecase: you are at your desk with a new laptop (or a friend), the router is in the other room and the password is long, and you can't find where you put the QR code the last time.
On linux, it could get the active wifi network from iwconfig and the password currently used from either wpa agent, seahorse or others.
It should present the password in a window, in case it contains an identifier.
