We have a guy at our dropzone. He is a lovely guy, very nice fellow. He started jumping in the late 80s/early 90s with his wife. They both quit when the got their kids. He started again like 6 years ago. One day, after jumping, his wife was there. At some point in the conversation she said "I don't get why you need all these rules, patterns and recommendations. We were all able to fly our canopies safely before without any of that."
I think she didn't realized how much of a difference it makes, to have 18 people in the sky at the same time with wingloads from 0.9 to 2.5, with respect to her times, when they had 4 people in the sky all of them with 200 sqft canopies. The size of the loads and the variety of wingloads makes proper canopy flying critical. Everyone should fly their canopies with everyone else in mind. And that involves in many cases not spiralling just for shit and jiggles. If you want to spiral down when you have 3 other canopies in the sky and you are perfectly aware of where they are, and how they fly, go for it. But that simply does not apply in bigger dropzones with loads with massive differences in wingloads.
