I’m not a reviewer, but it seems pretty obvious to me. I could be wrong! Imagine reviewers are bouncers at the nightclub… if you’ve got sneakers on then they’re going to tell you you’ve got sneakers on and turn you away. They’re not going to look at your footwear, check your ID, pat you down for weapons and the like… and then tell you you’ve got sneakers on and turn you away. It’s an inefficient use of time.
Maybe if an item is really close to getting approved, then it makes sense to go through everything, but not if it’s pretty far off the standard on the current submission.
