X-Auto-Login at Google

Below you can find evidence that Google is using the X-Auto-Login header in production.
Please see my other post for context: http://ignisvulpis.blogspot.de/2014/09/deviceautologin.html
 I am using "wget" to get gmail web page and the HTTP response contains the X-Auto-Login header.

I think that Google should standardize this.
Currently Google is using OpenID2 here but it is probably ease to standardize this with OpenID Connect.
