IMO, the fire code would be more about smoke control and keeping things secured when heat buildup occurs. The regular plastic ties will likely add more more toxic smoke to an area as well as melt long before the metal of the MC or armored cable does, which could release the bundles of cables and allow them to fall, creating even more property damage and additional hazards to first responders.
