Isn't this just .presentationDetents(_:)?

Is it just to support Presentation Detents pre iOS 16?

You can say this is the UIKit version of that API, since Rideau is mainly for UIViewController presentations through our FluidInterfaceKit navigation framework. As for functionality, Rideau offers more than what SwiftUI's Presentation Detents offer, since Rideau also lets you customize the header view appearance as well as handling of nested scrolling among others.
