In road racing we can heat soak the wastegates and potentially melt the bladders if we don't have enough airflow over the wastegate. Water cooling would keep the bladder cool and also prevent the spring weakening with heat soak, opening earlier and dropping our boost levels. I've yet to damage a bladder, but I have had boost fall off over a race as everything gets really hot. Whether this is just related to increasing intake temperatures or was the wastegate, is hard to say.
