This update simplifies how businesses can customize the website event registration process. By separating the registration logic, developers can now easily inherit and modify the underlying code, leading to more flexible and tailored event experiences. This change enhances the extensibility of our website event functionality.

Since this controller returns raw markup, it is impossible to inherit.

By splitting the controller `registration_new`, allows to manage custom developments with the inheritance of the prepare method instead.
