I would argue that "Quality Years of Life" is what 80% of people (both as individuals and as policymakers) would optimize for, if given a good metric and perfect information, and that "crude life expectancy" is only commonly used because it is so easy to non-controversially measure. So IMO it's not really moving the goalposts as much as "reminding us of what the actual goalposts are."
