Content metadata can be revealing, I reckon that's why the urls in the article say [redacted]. The title of the post gives away information. Even financially significant info in the case of announcements, for instance.
There are other ways unpublished urls may leak in - for example via sitemaps. Trying to lock them all down is lousy engineering. Instead just password protect the unpublished content and you're done.
