Cratered runways are a part of what WW2 was, thus why you see Spits upping from fields and such. Same reason why jets like the Harrier jump jet and STOL aircraft were invented...runways are a valuable assett, if bombed, create real problems for aircraft that need a long smooth surface.
I say let the damage be in there. My bigger gripe is Osties driving on through a bomb crater made by a 4,000 pound bomb harmlessly....
