I really wanted to add cell balancing but the PCBs are designed in way that it would require hardware modifications that I thought very few people would actually do, especially on the V7 models and up. I was also pretty burned out on this project by the end. I did add a way for you to at least monitor the cell balance level via LED blink codes so you know when the cells need to be manually rebalanced. You are correct that in the end, this project doesn't provide a ton of extra utility. Especially since another user from the EEVblog forum thread, dvd4me, found the EEPROM values you can reset to clear the permanent lockout on the original firmware.
