Captive portals are used for many, many things that aren't just internet access gateways. Many IoT devices use them to enter wifi credentials so the device can connect to the wifi router. One of my projects is an IoT device with a custom web interface that can be used from a cellphone when there are no nearby wifi routers for the IoT device and phone to connect to - the phone connects directly to the IoT device and gets the custom device control interface.
