All 120-volt, single phase, 15- and 20-ampere branch circuits supplying outlets installed in dwelling unit .... closets, hallways, or similar rooms or areas shall be protected by a listed arc-fault circuit interrupter, combination-type, installed to provide protection of the branch circuit.
The 2008 is asking for ALL of the outlets that are in dwelling including closets or similar rooms.
I can't imagine anyone installing a non AFCI dedicated lighting circuit just for the kitchen or the pantry.
