Thermostats control the flow based on the temperature of the coolant exiting the engine, but they do not control the temperature of the coolant exiting the radiator...

Two ways to fix this would be to have a thermostatically adjustable radiator block, or a thermostatically adjustable radiator bypass. Either solution would make the temperature of the coolant entering the engine constant regardless of ambient temperature or loads applied to the engine.
Is "too cold" coolant temp variation incoming to the block an issue?

Cuz if the thermostat says brrr I'm cold, it closes, then flow incoming to the block is restricted/stopped. The net result is pretty consistent coolant temp in the block pretty much whatever the coolant temp leaving the radiator is... right?
