We went in mid-September and tried to limit what we took into the parks; mostly we carried our phones, power banks and cords, snacks, hand sanitizer, Kleenex, and empty water bottles. We put that all in a see-through bag (the kind that's required if you take a bag to an NFL game). Literally every security person who did a bag search thanked us for doing that, and several said that they wish everyone carried a see-through bag.
That being said, when I wrote DLR with my post-trip letter (which I always do), I told them that the part of our vacation I was least impressed with was security. While I want to be safe, there are many ways to ensure safety while not diminishing the user experience. To me the biggest frustration was picking the "wrong" line. I don't mind waiting. I mind choosing one line that ends up taking 20 minutes while another line takes only 10. And recent research says similar things; people want equitability--they don't want to feel like they have gotten screwed. Disney promises a world class experience but won't pay for additional CM to manage security lines. A single line and a CM directing the front of the line to a particular security station may not reduce wait, but it would increase user experience because it would make everyone have the same user experience.
