I'm not sure I see how arguing for goodness as an overarching quality promotes more discussion than arguing for goodness of various qualities. Perhaps you get more disagreement, as people who may agree about each individual quality will argue about the value of each quality, but the comments about the art itself will be unchanged - it's merely the discussion about the relative value of each quality that flourishes when we feel we can measure goodness as a whole. Now, perhaps this is the discussion you would like to see survive. If you feel that making arguments for things like why novelty is more valuable than technique is important, then I can understand your perspective and agree that we lose those conversations if we use a multi-axis approach. But if you care about articulating why a technique is impressive, or why a piece speaks to you, then I don't think we need to be able to rank all art on a single axis to have those discussions.
