SNAP and Polarimetry

Hi all

I just wondering about a controversial question. I’m not an expert in polarimetry, but considering that SNAP now allows you to perform:

Polarimetric Matrix Generation (C2)
Polarimetric Classification (Unsupervised and Wishart)
Polarimetric Decomposition (H-Alpha Dual Pol and Model-Based Dual Pol)
CP Stokes Parameters

I know; Sentinel-1 is not the best option for polarimetry (ideally, it would be a quad-pol sensor) but I was wondering: ¿What can Polsarpro contribute that does not have a snap in dual polarization?

I would like to thank you all in advance for your attention!
