Well there is at least one reason that release notes are bad: any mention of any new feature or specific fix seems to trigger more scrutiny from Apple reviewers.

The more information you provide, the more likely it is that your app will be held up in review or you will get additional questions from reviewers delaying your release.

I generally still try to err on the side of including information in my release notes, but I have been bitten by this enough times that I completely understand this practice and sympathize with other app developers.
