Bottom line, it shouldn't increase the maximum temp the EGR cooler is exposed to and not make it any more prone to crack.

Without egr flowing gas, the temperature would always be cooler. Static gas sitting there would lose its heat.
With the coolant lines still there the static gas inside the cooler and pipe would be close to coolant temperature.
