aclWhereClause hook isn't called on CRM_Contact_Page_AJAX&fnName=getContactList

Step to reproduce:

create a module with

function test_civicrm_aclWhereClause( $type, &$tables, &$whereTables, &$contactID, &$where ) {
die ("Here be dragons");
}

And a user with access to civicrm but not access all contacts.

When you do a contact/search, you die as expected, but if you use the autocomplete for relationship:

http://example.crm/civicrm/ajax/rest?className=CRM_Contact_Page_AJAX&fnName=getContactList&json=1&context=relationship&rel=14_a_b&s=&limit=10&timestamp=1300024321779

it doesn't (and doesn't return any contact).

Is is the same issue for the list if you press enter
http://example.crm/civicrm/contact/view/rel?snippet=4&type=Relationship&subType=14&qfKey=d400348b91fb59c001c4a80605484600_9778&cgcount=1

P.S. For the love of API, why isn't it using the "get" function instead of that getContactList ? (if good reason, at least should migrate it to api v3, ping me if needed)
