@sebastianr yes, it literally is just like that when waiting for an answer. I had to prompt on the dev support forum for a question that had been waiting 6 months for an answer. I know they are a small group for a big game, but anything flight model related seems to struggle to be answered, either satisfactorily or at all.
In terms of 'quietly working on it', I have been doing that for far too long for it to be economically viable😂 nearly a year now, and I have run out of ideas given that most of the Asobo flight model does not really make sense either aerodynamically or geometrically, and the SDK has been followed as far as was possible given the state of it back then and, to an extent, now!
So we really are in their hands unfortunately, and believe me I am as disappointed about that as you are.
