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.

I think this means the one-true-master copy of a man page is now the public .md file.
All contributors can now change and improve man pages, and would be expected to make necessary man page updates when making other changes.
(Which is great, I just didn't see it being explicitly said.)
