Google deprecates OpenID 2.0, moves to OpenID Connect

Yes, it looks like Google is moving on from OpenID 2.0 to OpenID Connect, which is the new standard [0]. It appears that OpenID 2.0 login will be kept for compatibility, though [1].

Google+ Sign-In is an implementation of OpenID Connect, with some nice features built on top:

"Google+ Sign-In is built on the OAuth 2.0 and OpenID Connect protocols. It supports over-the-air installs, social features, and a sign-in widget on top of standardized OpenID Connect sign-in flows. Google+ Sign-In works for all users with a Google account, whether or not they have upgraded to Google+." [2]

Ridiculously misleading title. Yes, OpenID 2.0 is being deprecated, yes they'd like you to move to Google+ Sign-In, but you can also move to OpenID Connect[0], which is a saner realization of OAuth 2.0 than OpenID 2.0 was.

And this is made clear right on the page linked to. There is no way anyone acting in good faith could draw the conclusion that you're being required to move to Google+ Sign-In.

It looks like the OpenID Foundation considers OpenID 2.0 obsolete and OpenID Connect is the new thing: http://openid.net/developers/specs/

What does this mean for users like me who use Google’s OpenID as the backend for OpenID delegation? Will I still be able to log in with “http://roryokane.com/” as my OpenID if I keep the delegation tags at that address pointed to Google’s servers, or will I have to switch to a different OpenID provider? This Google+ integration won’t work for me, since none of the OpenID sites I am signed into even know that I have a Google account; they just know my pre-delegation OpenID.

After migrating an app from old OpenID to this, I think I'm done with integrating Google services for a while.
