I argue that there's an mapping in the opposite direction: if you add extra nodes to any problem that looks like a problem where TDT and CDT disagree, and adjust which node is the decision node, then you can make CDT and TDT agree (and CDT give the "TDT solution"). This is obvious in the case of Newcomb's Problem, for example.
I guess it's true that CDT needed lots of ideas to work. TDT has one idea: "link counterfactual decisions together." So it is not an unreasonable view that TDT is an addendum to CDT, and not vice versa, since CDT is intellectually richer.
