Call me unconvinced. Almost all of those goals have come out just weeks before a new playtest packet which addressed it was introduced. It's almost like they're a few weeks ahead of us in internal testing (which is fine and which they have said), and when they find something cool, they tell us about one of their "design goals," polish up what they already had, and then reveal it as a fulfillment of those goals. It's like rolling a Craft check first, seeing what the result is, then deciding what you were trying to make based on the result. The packet after they introduced bounded accuracy, they had let it slip a lot, and Mearls was talking about AC and attack bonus scaling with monster level again. These aren't design goals, they're drive-by marketing slogans.
