will the update allow the "seamless" use of "user(aircraft)state auto docking by SODE" with GSX ...... on arrival & pushback.
Please explain what do you mean with this.
GSX had auto-docking for user airplane since a long time, if you enable the Automatic service option, which I still think it's not the best idea, since it cannot prevent issues like jetway crossing if there are more than one jetway solving with more than one door.
The update will add jetway support for AI, nothing will change for the user airplane, which will auto-dock ( or not ) depending on that setting, as it always did.
