I get what you mean regarding Tomorrow Never Dies and the fact that it refers often to the "Surrender" track by k.d. lang more than it does Sheryl Crow's actual theme, but the Casino Royale score "quotes" "You Know My Name" all over the place in that movie.
...yes, that's what I was trying to say had happened in those films - and by contrast it looks like that won't

Well, we don't know that for certain yet. It's entirely possible it could go either way. Just because Newman isn't credited on the song's sheet music cover page doesn't necessarily mean he didn't contribute to it or that he won't lift from or refer to it with his score. We'll find out when the full album is out in November.
