The only logical argument to do so is for loyalty, but unless other airlines do this, I don't think you can really make that argument.

You are saying DL should give up say up to $14000 in revenue ( 2x RT TPAC) to upgrade a passenger from a lowest coach fare to a J fare, because they are a Diamond??? When they might not even give that revenue to Delta all year? Yeah right.
