I'm not sure where you got that idea. The inconsistency is from a few years ago when they pushed for rounding the windows more than they have been for years, and then a further rounding in Tahoe, but not all developers following suit. All of Apple's own apps use the latest iPad/Fisher Price-esque border radius, but most third party apps are not. I can compare Safari to System Settings and they have the same new rounding. It's nothing to do with utility vs "main" (whatever that is)
