KVS, W is not the business upgrade class for SA (as stated in the FAQ). SA now uses O,I,X for award and upgrade classes the same way that many *A partners do. As far as I know none of these is visible using any of the KVS methods or EF.
BTW I mailed AUA as you suggested (using the "mailto" button on their site) to ask if they were going to recognise SA as a *A partner anytime soon - and the mails just bounced back as undeliverable.
