It sounds to me like what the author is really saying is that a quantum theory of gravity would look like some of these modified gravity equations in the classical limit. Of course it would be nice to kill two birds with one stone and knock out quantum gravity and dark matter with one discovery. I am curious if some of the proposed theories could be made to look like that.
