Hollywood started allowing costumes middle of last season (or maybe it was the year before). It was definitely discussed here. I'm sure they know the protocol by now.
I'm not sure how it impacted ops/security (I wasn't on the ground), but they seem to be pressing ahead. People have basically been wearing costumes since 2018 with folks dressing up as the Stranger Things kids, so, I guess it was a losing battle.
