The original CMP intent was to require them throughout the house back in 1999, but it was thought to have been too disruptive with a new device so they limited them to bedroom receptacle outlets. Then they expanded it to all bedroom outlets, then to more areas of the house.
Soon they will be exactly where they originally wanted to be in 1999, with everything in the house protected with AFCIs...and it only took us a little over 10 years to get there.
