Given that this is a public interface on a public class of a public module, I decided to add this new method as a `default` method to prevent any potential breakages of any non-JDK implementations of this interface. The internal `jdk.internal.net.http.HttpRequestBuilderImpl` which implements this interface, overrides this default implementation to use an implementation of its own.
