Again, I think what people see as "getting rid of desktop design patterns" in macOS is mostly aesthetic. Mac apps remain Mac apps, they retain all the aspects of their interfaces that make them Mac apps.
More evidence in the way iPadOS 26 adopts certain aspects of the macOS interface, but does them in an iPadOS-oriented way that you wouldn't really say the two OS are converging, more that they're doing really weird impressions of each other — but underneath the grease paint, the same actors as always remain, each with their strengths.
(In saying that, System Settings is an abomination)
