Dallas has been characterised by Love Field not only remaining open but carriers bursting to get in there and circumvent any restrictions. I think it has more passengers now than when DFW opened.
CDG has not supplanted Orly at all, and the majority of French short haul ops still go from there. It's rendered it a difficult place for connections.
Changi and Hong Kong both seem to be closer to the city than even Heathrow is.
Fundamentally, neither airlines nor passengers like airports that are far out. Commercially they don't work well, and notwithstanding older terminals the paying customers value convenience over some pangalactic architect's ego trip.
