Good move. In relation to it's size, I didn't see nearly as many reports of comic-con being a spreader event compared to other conventions. I think the reason for that was the mask requirement. Masking works.
There was another conference at the San Diego Convention Center a couple of weeks before comic-con. Same convention center, same ventilation, same BA.5 surge, same Gaslamp for people to hang out in, but no mask requirement. People were quite upset afterwards that there wasn't more done like a mask requirement when the reports of positive covid cases started to pop up.
