It did?

It is possible, I suppose. But since you had to go to home screen first to lock the screen anyway, it was only exposed by accident, when the screen locked itself due to a timeout. Which happens pretty much never

I for one welcome the fact that when I unlock a thing - be it a desktop PC, a phone or a garden shed - I find it in exactly the same state as it was before I locked it. Why would anyone want anything else is beyond me.
