I agree with your comment "It's all about guaranteeing that a recovery will work if you use log_mode NORMAL"
Infact in my case the PIT recovery had failed with log_mode=NORMAL and worked with log_mode=OVERWRITE, this made me share my experience and understand from others on their experience
I would try and do some more tests if we are able to in future and share my feedback if I find any results otherwise
Thank you for your comments on this
