This is done regularly at the start and end of a new release cycle, adding to the burden of creating a new release. It is also done (if any of the reviewers knows about the process) whenever an Oracle engineer updates a man page. If a community contributor changes the behavior of a tool, an Oracle engineer needs to change the documentation for them, since they cannot do it themselves.
