May we get rid of “Flat Airports”?

Infinite Flight has always included “flat airports” disregarding the actual terrain in some airports (e.g. Courchevel, Lukla; there’s also a slight curve in KSEA and more). Some of their surroundings look like a “wall” and others look like a high plateau.

What’s the reason that IF’s unable to mold terrain in airports?

(That won’t be a feature request since I’m just curious for now)

Obviously they would if they could, not sure the exact reason here I’m sure someone does though.
