I don't really have any clear idea about that, but there was a discussion about DPB vs reference picture lists some weeks ago. Is there some mail thread with a rationale about it, some IRC logs I could look at or could the people involved in the discussion provide some additional background at this point? IIRC we also talked about removing the DPB or at least renaming it, but I don't have a clear idea of the outcome as well.
