Thanks for the info.
From my point of view and if I am allowed two share my two cents, I would say that even if ESA sensors should clearly be the top 1 priority, giving the tools that enables users to use others sensors is also beneficial for the Sentinels, because the sensors are not competing each other but rather complete themselves quite well. The situation is however inversed when looking at RS softwares.
Sentinel-1 is not and will never be a full quadpol L-band SAR. Giving the tools to use SAOCOM directly at launch encourages users to use SNAP, because it will allow them to mix so many sensors all-together.
But again, this is my two cents on the subject
