API Case Entity and Get Action can not be called without search fields

In most API's the Get action can be used to get all of them (contacts, activities etc.). This can not be done for the Case API, if you call it like this:
Code: [Select]
$apiCases = civicrm_api( 'Case', 'Get', array('version'=>3 ));

an error message is returned:
Code: [Select]

{ "is_error":1, "error_message":"Missing required parameter. Must provide case_id, client_id, activity_id, or contact_id." }

From a consistency point of view I would say it should return all cases.
