+The [stay of execution](http://source.ikiwiki.branchable.com/?p=source.git;a=commit;h=6660fd643bf3b65745d62b24cb16fef1b5205207) of Google's OpenID support, possibly until 2017,
+_only_ applies to ikiwikis that had already been live and whose `openid_realm`s had been
+seen by Google in at least one request by 19 May 2014, or whose admins had emailed Google to
+request an extension by 15 June 2014 ... this according to Miguel Andres's answer on
+[this thread](http://stackoverflow.com/questions/23773275/changed-domain-error-openid-auth-request-contains-an-unregistered-domain).
+
+Google will not work as an OpenID provided for any ikiwiki set up since that time.
+
+So, probably that Google option shouldn't be in the OpenID selector; maybe there
+should be an option: default _off_, can be turned _on_ for an established ikiwiki
+instance that is known to be grandfathered.
