HTTP_X_FORWARDED_FOR

Any plans on adding in something like below, to get the actual IP address if site is behind a load balancer?

if ( isset( $_SERVER['HTTP_X_FORWARDED_FOR'] ) ) {
	$http_x_headers = explode( ',', $_SERVER['HTTP_X_FORWARDED_FOR'] );

	$_SERVER['REMOTE_ADDR'] = $http_x_headers[0];
}
