I think that’s the wrong way of framing it. If, before the launch of the iPhone, you asked what people wanted from their phones you’d be there a very long time before anyone described something like an iPhone (no buttons, capacitive touch interface, etc). And yet, once they were offered it, people flocked to it.
This regulation is targeted to devices with poor battery lives. Just because it hasn’t occurred to people to ask for the feature doesn’t mean they won’t appreciate it.
