I tried to reproduce extra logging after this PR had landed in jdk17u-dev, and I don't think it is a problem. It was a huge problem before [JDK-8319896](https://bugs.openjdk.org/browse/JDK-8319896) yanked deflation from the final audit, and which point logging became massive. In JDK 17u, we still do deflation at final audit, so this is a non-issue.
