No. "You have to unlock your iphone first" is such a hindrance to using Siri for anything more than setting timers and alarms. If you're doing anything that involves gloves or a mask or getting your hands messy, like in a kitchen or something, it is just so frustrating. How about making a toggle so I can choose to be slightly less locked down for Siri, and I take full responsibility if I get hacked because of it.
