Thanks for this @KevFan ... I probably should have done this quicker, i.e. before anyone hits the issue indeed when running latest, my bad. This additional change will probably be needed to be added and I wasn't sure if anything then in turns affects the Kuadrant CR or if we just pass it "blindly" along... /cc @eguzki
