Hi Sir
I generated a report for around 200,000 commits (v4.13..v5.8), and
found that this rule was being triggered only 6 times. Statistically
this doesn't seem much. Is it still advisable to mention it in the
commit message?
Although, there's a possibility that user fixed this issue after
receiving the warning manually before committing.

Thanks
Aditya
