Thank you. The title plays on the idea of deriving quantum mechanics from the rules of “common-sense” probabilistic reasoning. Suggestions for a better title are, of course, welcome.
In my view this is not so much “QM foundations” or “adding to physics” (one could argue it takes away from physics) as it is an interesting application of Bayesian inference, providing another example of its power. It is however interesting to discuss it in the context of MWI which is a relatively big thing for some here on Less Wrong.
I agree with everything Scott Aaronson said there, actually. As for the common sense, apparently our definitions of it differ. Furthermore, while I agree that this paper might be an interesting exercise in some mathematical aspects of Bayesian inference as applied to something or other, I question its relevance to physics in general and QM in particular.

Regarding testability I’m reminded of the recent discussion at Scott Aaronson’s blog: http://www.scottaaronson.com/blog/?p=1653
