Actually, if you change the action in form (maybe form to unlink google and wiki account) to /Create you can create a new User account, also when you are logged in and the google id is linked to another account (the Google id is still linked to the "old" account, so no account compromise).
Change 142807 had a related patch set uploaded by Florianschmidtwelzow: Disallow creation of wiki account if Google id already connected https://gerrit.wikimedia.org/r/142807
