I don’t have time right now to go into details but it was surprisingly simple, from a filter rules perspective, to create an “iMessage only” access point.
So there is no isolation from peers, but also no other usage of the device.
We turn it off completely at 9pm.
Edit: oh, the other important detail is that they have no-data SIM cards. Tello sells text and talk only sims for $8/mo or whatever. Weirdly, when they are away from home, apple finds a way to tunnel blue bubbles through (sms only) … not sure how … bottom line is, at home, it’s iMessage or nothing.
