Not sure what you mean by this. But we are opening block_group based on the
condition which you want to eliminate.

Setting a flag will mean a lot more refactoring. BlockGroup can arise only in 2
cases now which are covered by the checks currently. If we need to use flags,
then we might need more than one flag (one each for different types of case
that could trigger opening a BlockGroup) to make the refactor worth it. If you
think it will be cleaner that way, please let me know. I can make the change.
