Yes there is a reason, you would cook some engines even before taking off. (Merlin III for instance, esp. in a Spitfire where the water rad is being blocked by the landing gear) Regarding Mercury IVs, in the real life manual it says rads open on the ground, shut on the take off run hence my comment about 'unrealistic', it's pretty much the other way round in game.
