You are absolutely right. The possibility to control coolant temperature is a sign of progress. Engines can warm up faster and use different temperatures for different load points. The engine in my daily driver uses fuel consumption optimized coolant temperature of 107 °C (225 °F) under low load. Under high load the temperature will be lowered to 85 °C (185 °F). Electric thermostats make it possible to optimize coolant temperature for engine warm up, fuel economy and power. With traditional thermostats things get compromised.
