TIL about Checkstyle's JavadocPackageCheck. Thanks, @eddumelendez. I wonder if we should add this to Spring Java Format, alongside the existing Javadoc-related checks.

I've opened https://github.com/spring-io/spring-javaformat/issues/328 to made JavadocPackageCheck part of the default Spring checks.

Thanks very much, @eddumelendez. I've just kept the package-info for GraphQL metrics. The other changes will be taken care of as part of a Java Format upgrade across all maintained branches (#31166).
