Lock Screen Widget Limitations initialcharge.net

I am with Mike Rockwell in my confusion about the limitations of Lock Screen widgets in iOS. It seems plausible for there to be design intent, but it is hard to see why I should not be able to place a rectangular widget on the right-hand side and place an Obscura camera button to its left. Surely it should be possible to improve accessibility for left-handed users without restricting them from using certain types of widgets in certain ways.
