Heh, I see that you edited it to add more since I originally pressed "Reply".
You imply Google is "evil" because they write "only about Google+ SignIn", but I'm not seeing that. The link that you provided has two sections, migrating to Google+ SignIn if you are already using a Sign In with Google button, and a section on how to migrate to just basic OpenID Connect. It doesn't seem hidden away like you are implying.
On the same page, they list how to migrate to OAuth 2.0/OpenID Connect, and even say "If your OpenID 2.0–based app does not need social features or is on a platform not supported by Google+ Sign-In, or if you want to work directly with the OAuth 2.0 REST APIs, then we recommend migrating to Google's OAuth 2.0 login (OpenID Connect) solution, as described below."
