Thank you to the moderator who added Verizon to the title. I thought of that too late.
I don't think this is a 4.3 change, but probably something I just noticed due to checking for features. It probably relates to my using Delayed Lock and having the Swipe to unlock page activated while at home rather than Pin. Anyway, I can now use both Home Screen Widgets and Shortcuts. The shortcuts in particular are pretty nice.
