Very clever.
IoT pairing is a tricky problem because phone/laptop devices give a very limited API for communicating with a new WiFi device that isn't yet on your WiFi network.

I'd prefer an out-of-band option, like "physically connect the new device to the IoT hub's 'new device' port to configure it automatically before moving it to its permanent location", or "scan the QR code on the new device, which contains a public key that the IoT hub will use to broadcast the WiFi credentials over RF", but I understand that at least for mass-market residential products, that's unlikely because it generally involves more components on each device.
I figured this out when I tried to debug why the pairing didn't work from my phone, but did from an old Samsung A2: the iot device only had a 2.4ghz module, my new phone was on 5ghz...
