expanding the google map api_url function

the api_url function defined in clas-gmaps.php has a beautiful avf_google_maps_source filter that allows the google maps api url to be filtered. While this is great for updating the api version, any new arguments added to the $api_src array will be ignored.

For example:

add_filter( 'avf_google_maps_source',  'pi_google_maps_url', 10, 1 );
function pi_google_maps_url(array $api_src){
                // update the current google maps api version
		$api_src['version'] = '3.35';

                // add delicious new arguments
		$pi_args = array(
			'libraries'	=>	'places',
			'language'	=>	'de',
			'region'	=> 	'DE'
		);
		$new_args = array_merge($api_src, $pi_args);
		return $new_args;
}

Will update the version, however ignore the added arguments because a new $args array is being define and this is used to create the query args.

Any chance of either a) merging the $api_src into $args after the avf_google_maps_source filter is applied:

$api_src = apply_filters( 'avf_google_maps_source', $api_src );
// clone $api_src into $args
$args = $api_src;
// remove the version and source from the $args array
unset($args['version'], $args['source']);

or better yet b) simply add a new filter for the $args array:

if( $api_key != '' )
{
			$args = apply_filters( 'avf_google_maps_args', $args );
			$args['key'] = $api_key;
}
