KORD for MSFS is definitely listed on all places where it's supposed to be:
- The MSFS products page.
- The Buy page on the store page.
- The FSDT installer.
I don't know why you don't see it, but the airport not only is fully supported, but it has been just updated for MSFS 2024. However, the update with new taxiways and th new half of Terminal M, is a completely different matter. Obviously planned, but we don't have an exact timeline for it.
