I think the language adopted by Florida in re: bonding metal studs would be a good addition to the next NEC revision. Pretty simple, pretty cheap, and would eliminate the risk of energizing a metal studded wall section. Just require one metal, grounded box attached to each partition/section, thus grounding the whole section. That should be pretty cheap to implement, and, as the news story about the tragic death of the dryer installer demonstrates, this is an issue occasionally.
