I have not experienced reviews from data editors since the AI boom but now that I use it to review my own codes checking whether they do what the paper says they do, I must say that it changes everything for refereeing codes now. Make them check and edit a report that the authors must answer to
EC is truly an amazing conference which reinforces the link between econ and CS. It was my first year as SPC, it was nice and I confirm that the papers are terrific!
