Honestly, once the cells are discharged to 3V or thereabouts, there is very little electrical energy left in the pack, and I'm unconvinced that it's necessary to drain it any further.
Take your 3v/cell pack and short the + and - while on video. Then do the same with a pack at 0v/cell.
You have to remember most packs are not single cell. A 3s or 4s pack would still have 9 - 12 volts of energy and I'm guessing wouldn't have any issue starting a fire.
