the reason they adopted the AFCI in bedrooms is because of picture placement on walls. many installations ran the romex up the stud, stapled. the homeowner put up a picture not knowing where the stud was and pierced the romex with a nail or screw. this created a high resistance area that maybe wouldn't trip a normal breaker but would heat up over time creating a hazard. the AFCI like a GFCI would trip upon this penetration.
