Maybe. Then there's the matter of Dallasites being able to fly in and out of their city or DFW as they choose. While Fort Worth citizens, whose taxes are also paying for all this, cannot fly from their own city and must drive to DFW, which is midway between Dallas and Fort Worth.
Fort Worth is probably fighting to not end up with the short end of the stick, but I'm just surmising here.
It's not my fault they closed their airport. (BTW, IMHO, Congress should have nixed ALL funding for O'Hare expansion when King George trashed Meigs. If Chicago has adequate capacity that it doesn't need Meigs, it has adequate capacity).
