Different people enjoy their coffee at different temperatures. Those who enjoy drinking steam should be able to make that choice without being "protected" from themselves.
I'd love it if the serving temperature of the coffee became more of a prominent option - I personally have to let freshly brewed coffee sit for ~20 minutes to be drinkable, and I even go so far as to delay adding cream (if I am going to) so that it loses heat quicker. But I still respect that my preference isn't universal.
