Swiftui 3 API cleanup: is it achievable with custom styles?

Swiftui 3 and iOS15 gave us the possibility to use styling more easily, so instead of

.pickerStyle(WheelPickerStyle())

we might use

.pickerStyle(.wheel)

At the same time, we can determine custom styles, for example:

struct CustomButtonStyle: ButtonStyle {
    func makeBody(configuration: Self.Configuration) -> some View {
        configuration.label
            .foregroundColor(Color.blue)
            .background(RoundedRectangle(cornerRadius: 12).fill(Color.red))
            .scaleEffect(configuration.isPressed ? 0.9 : 1.0)
            .frame(width: 40, height: 40)
    }
}

However, to use the above custom style, I have to write

.buttonStyle(CustomButtonStyle())

How might I achieve the possibility to use the custom style with a simple modifier like this?

.buttonStyle(.custom)

We can create extension to ButtonStyle, like

extension ButtonStyle where Self == CustomButtonStyle {
    static var custom: CustomButtonStyle { CustomButtonStyle() }
}

and then use it as

.buttonStyle(.custom)

Tested with Xcode 13 / iOS15

Note: this approach does not work with Xcode 12
