> So.. all this drama over an alert(yes/no) box?

A simple yes/no alert box is not "[...] specifically to resist coercion, ensuring that users aren't tricked into bypassing these safety checks while under pressure from a scammer". In fact, AFAIK we already have exactly that alert box.

No, what they want is something so complicated that no muggle could possibly enable it, either by accident or by being guided on the phone.

I imagine what they're going to do involves a time delay so a scammer cannot wait on the phone with a victim while they do it.
