Comment (by tywayne):

 {{{REQUEST_URI}}} was used to ensure a return to whatever view of
 widgets.php they actually came from.

 For example, let's say a theme or plugin provided a filtered view of
 widgets.php, showing only widget areas for specific layouts/templates
 using a query string (iThemes Builder does exactly that.)

 If we explicitly point them to widgets.php, they'd lose the filtered view
 they came from.
