What is the clou about the AN9525? 
It is elaborating about a pre filter feedback design, so they do no need to handle the phase step of the output filter.
Loop design of AN9525 is following the traditional way.
Where do you see an overlap to our discussion?

On request during a side discussion and for better understanding:
Please be aware the bode plots (post#64) and Nyquist plots (#post75), where derived from the design according post#11 basically.
R32, C8 are showing a simplified version of the real shaping-PI-network.
