Really? Because the stall for me was that "sign in with Google+" demands permission to read my email address book.

"Fuck" and "you" are the only things that come to mind there.

The demanded google OAuth scopes are:

data-scope="https://www.googleapis.com/auth/plus.profile.emails.read"

as seen in the page source code. Not your address book.
