I'd be interested in a top-level post — I had been meaning to ask about it, in fact. I've read about DST briefly and had been wondering (1) if in practice it is actually useful for anything you can't do as easily with pure Bayes, and (2) if they are theoretically isomorphic or if Bayes is strictly a special case of DST.
In my opinion, using DST usually adds unnecessary complexity to problems that can be sufficiently solved in a Bayesian framework. Then again, I think that the same thing can often be said of descending from a Bayesian to a Frequentist approach, which is to say that most problems are simple, and properly using any framework is enough to get a good answer. See neq1's post that inspired my original comment.
That said, I work on problems that I have solved both from a Bayesian perspective and from the perspective of DST, and I have found the former lacking. The...
