We need to differentiate between batteries and cells. A battery is a group of cells. It is never a good idea to discharge any battery to zero because you will pull some of the cells below zero which means those cells are reversed charged. In NiCads this causes crystal growth that shorts out the reversed cells.
If this 'hack' actually reads individual cell voltages, it would be a great addition. If not, it will probably lead to shortened battery life. Anyone think Nissan will warranty a battery when their BMS system has been bypassed? After all the purpose of the BMS (battery management system) is to protect the battery by keeping the cells in balance, monitoring cell temperatures, and avoiding under and over charge.
