When I copied this it changed the strike through text but you can get the general idea. What it comes down to is all 15 and 20 amp 125 volt circuits will require AFCI protection. Personally I agree with this proposal.

Substantiation: For the past three NEC cycles, CMP 2 has reviewed extensive amounts of data and information pertaining to the benefi of AFCls for the protection of dwellng unit branch circuits. After careful consideration the panel
decided to required AFCls on branch circuits that supplied bedrooms as a means to gain experience and to put the application in an easily defined area.
AFCls have had an excellent track record in the field and their installationluse have found numerous wiring errors and in addition they have found wiring damage and equipment damage that could have been potential sources of fire.
With the experience gained, it is an appropriate time to expand AFCls to all 15 and 20 ampere branch circuits in the dwelling. There is no basis for limiting the protection to circuits that supply only bedrooms and the increased protection
is needed for other circuits. This expansion wil continue the effort to address fires of electrical origin in dwellngs.
The text has been modified to apply to all 120V 15 and 20 ampere branch circuits that supply outlets in all locations.
The second paragraph is proposed to be deleted since it is no longer applicable.
