I'd liked to get some insights into how others interpret the code regarding AFCI and the NEC 2015 code.
Here's a hypothetical:
Arc fault protection is omitted for outlets outdoors, garages and crawl spaces. Granted these have to be GFCI protected.
Now say I add some outlets outdoors and I have a switch in the master bedroom to control the outlets. Even though all the outlets but one are outdoors because the switch is technically an outlet, this would require arc fault protection in addition to GFCI protection.
