Good point about the temp of cold water coming out of the tap. Tap water temps would be substantially high in moderate climates, then northern climates. In a lot of small towns, your water comes from well(s), so it's fairly stable yr around but going through the water system to get to your house changes significantly in the summer versus winter.
Some people can get away with very hot temps from a gas WH, because of the cost factor of natural gas. Propane has a higher BTU content, but it's much more expensive than natural gas.
As often the case, modern detergents are a chemical cocktail tailored to be used with warm water for maximum efficiency. Eugene makes a good argument about breaking down the detergent enzymes in hot water.
