It makes explicit use of the soft breaking of time diffeomorphisms by the inflationary background to organize the operators expansion in the action of the Goldstone mode $\\pi$ associated with this breaking. Despite its ascendancy, there is another method for calculating $\\zeta$ correlators, involving the direct calculation of the so-called Horndeski action order by order in powers of $\\zeta$ and its derivatives.
