although more than one aircraft has the "chocks in" facility eg PMDG 737NX.
That's not the issue, we already recognize several airplanes with wheel chocks such the NGX, several Captain sim models and the Airbus X too, but as Pushback constraint, meaning GSX will not allow you to start Pushback until you remove the wheel chocks.
This issue with the Airbus X, is that according to your report, it automatically removes Brakes when wheel chocks are applied, and this is a new thing that no other airplane with chocks has ever done before.
