What would you gain from actual analysis of a debug version of one OS build that will be completely different in 6 months, perhaps even before that? Additionally, getting that debug version does actually require signing a restrictive license... What you will find is mostly reasonable debug data, feature click and run traces and OS memory and driver state dumps. Obviously some of this might be critical data nobody should ever get.
