Even if EUM doesn’t get “utility”, I think it at least gets “utility function”, since “function” implies cardinal utility rather than ordinal utility and I think people almost always mean EUM when talking about cardinal utility.
I personally care about cardinal utility, where the magnitude of the utility is information about how to aggregate rather than information about how to take lotteries, but I think this is a very small minority usage of cardinal utility, so I don’t think it should change the naming convention very much.
