Arguably all your IoT devices already do. There were multiple startups advertising "routing at the edge" or some other such bullshit maybe ~5 years ago. I have no idea what happened with those ventures but these days multiple ISPs offer the general public roaming WiFi access via the APs of their customers so I think it's safe to say that ship has long since sailed.
Come to think of it how cheap are LoRaWAN radios these days? That's another option.
Amazon sidewalk is a much bigger threat in this regard. I'm really glad we don't have this in Europe.
