Currently, because the font icons and styles are contained within the same stylesheet, if someone wants to customize the look of the widget they need to use !important declarations and very aggressive selectors. If you were to split these into two files, it would add an extra http request but it also would allow for much more flexibility.
With these decoupled, developers can now de-register the styles and unhook the function that outputs styling in wp_head. All the icons and the cool widget, none of the default styles.
