Your comment here makes it sound like the FDT paper said “the difference between UDT 1.1 and UDT 1.0 isn’t important, so we’ll just endorse UDT 1.0”, where what the paper actually says is:
In the authors’ preferred formalization of FDT, agents actually iterate over policies (mappings from observations to actions) rather than actions. This makes a difference in certain multi-agent dilemmas, but will not make a difference in this paper. [...]
As mentioned earlier, the author’s preferred formulation of FDT actually intervenes on the node FDT(−) to choose not an action but a policy which maps inputs to actions, to which the agent then applies her inputs in order to select an action. The difference only matters in multi-agent dilemmas so far as we can tell, so we have set that distinction aside in this paper for ease of exposition.
I don’t know why it claims the difference only crops up in multi-agent dilemmas, if that’s wrong.
