[IOT] network scale

I haven't yet made time to deeply review and post at length about the IoT XEPs. However, I've looked at them all briefly and I have a high-level question about their focus and intent. Several of them mention use cases involving millions of devices on an IoT network, and even millions of devices behind a single JID acting as a concentrator. Do we truly think this is a realistic scenario? Most of the use cases I hear about from customers (not involving XMPP) as well as the real-world usage of XMPP I know about (e.g., in demand-response systems) involve perhaps a few hundred edge devices (sensors, actuators, and the like) at any given deployment (e.g., at a factory, office complex, oil refinery, or construction site). Personally I do not see a need for millions of endpoints behind a single concentrator JID. I don't think I even see a need for millions of endpoints on any single customer deployment - tens of thousands seems a lot more plausible. Perhaps the authors were thinking about a single central server at an XMPP-based IoT service provider handling that many endpoints for multiple customers across all of their physical locations?
