EA reflects too much on the nature of the E and not enough on the A. I'm partial to your points here.
I think the concept behind nudging is sound even if the way it's been studied don't replicate. It's as simple as changing the default option from one choice to another, which is widely accepted as significantly changing the ultimate user choice. I think this falls under the original book's definition of nudging as "… any aspect of the choice architecture that alters people’s behavior in a predictable way without forbidding any options or significantly changing their economic incentives.”
