In every kind of utilitarianism, including revealed preference, utilities are assigned to outcomes. The varieties I've described, and revealed preference, just disagree about how to assign values to outcomes.
These are different mechanisms to theoretically quantitate utility, but do they actually have implementations? (Revealed preference is unique in that it's an implementation, although a post-hoc one, and defined by the fact that the utility is qualitative rather than quantitative - that is, utility relationships are strictly relative)
None of these actually assign utility to outcomes, they just tell you what an implementation should look like.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
