> What their mental model is for what "Wi-Fi off" is doesn't matter
It always matters if you're trying to minimize user frustration and confusion. The mental model determines what the user expects their actions to do.

I don't think anyone (certainly not me) is arguing that this isn't a useful feature for the phone to have and is what many people want, at least some of the time. The argument is that the feature's behavior should be clear rather than misleading.

Again, fine, but don't suggest one thing and silently do the "better" thing. Either allow the user to confirm the behavior, or create a UI that clarifies the behavior so people aren't misled into believing that "off until 5am" or "off until you move" means "off."
