The worst report I've ever made is the one I've intentionally omitted from the report. At that time, I thought it was a minor mistake, and I was embarrassed and didn't report it. But if you don't report it, there won't be any progress, and you won't be able to deal with it right away, and you don't know how things will develop. In addition, there have been reports of incorrect content (numbering incorrect or incorrect core content). It reduces mistakes, but seems to have lost trust.
