In my opinion, all 3rd party FFB tools will remain tools until the FS2020 SDK gives correct flying surfaces forces data like in X-Plane11 for example. Otherwise, you can approximate a “feeling or reality” with FFB but it will only be approximate.
It is the same problem with 6DOF consumer motion platforms which are rolling and pitching the platform according to the aircraft orientation, whereas they should only be concerned in orientating the platform so that the G force (real) is as much colinear as possible to the G force (virtual).
