For neutral at switch locations exception (or rather other than the following).. 404.2 c 4

what would be the theory why a neutral would not be required at multiple switch locations in one room?

thanks
 
I assume you mean 404.2(C)(5) 2014.

(5) Where multiple switch locations control the same lighting
load such that the entire floor area of the room or
space is visible from the single or combined switch
locations

The substantiation from the 2014 ROP contained this:

If a three-way switch loop controls the lighting in a space, and the switches
both see the room, why force a grounded conductor into every switch location?
Very frequently three-way switches will be arranged in a two-gang arrangement
where one of them will be on the opposite side of a wall from the illuminated
space it controls; how could that switch ever be replaced by an occupancy
detector? Note that 210.70 requires switch control of lighting loads in a space,
but the switch does not need to be in that space.

anyone's thoughts on 404.2(C)(4)2014 -

(4) Where a switch does not serve a habitable room or bathroom.

Would that exclude switches for lighting in/at hallways, stairways, garages, basements (unfinished), closets, utility rooms, pantry's, porches, etc. from this requirement?

Something that never occurred to me before and I maybe figured some of those places were required to have a grounded conductor at the switch. Yet many of those locations mentioned would be prime candidates for occupancy sensors so that if users would forget to turn off the lights they will automatically turn off anyway.

Glancing through the IRC minimum reqs of what defines a habitable room I would say:

hallways, stairways - yes
garages, basements (unfinished) - maybe
closets, utility rooms, pantry's - more often than not in average home. ~2000 sq.ft
porches - yes
