Single post in Delta update proposal [vote!]

All right, yes, assuming you notice it. It's another burden for users to check but I suppose that could work. What if you don't notice? What if you don't care at the time but, say a few months later, you decide you want to DP it? What then? With the proposed change, S/A/M sales would be for the specific purpose of acquiring that S/A/M. None of these hypothetical scenarios would be relevant, because if you want DP then you just trade for DP in the first place.
