I know Wordpress.org sends a header called X-Hacker or something, telling people who see the header to look at their jobs page and tell them about the header.
The X-nc header is related to the cache. The GP is correct in that these headers used to be sent on wordpress.org and wordpress.com, but it appears they are now only sent on automattic.com
