I have to say the same with VA's application for xx-DPS-PER. They really only applied as a backdoor way to get onto PER-DPS, and unsuccessfully tried to get the rules changed when Australia's IASC (on behalf of Indonesian authorities) stated that the domestic legs are required to be operated from the international terminals.
On another note, Batik Air Indonesia might breath some sigh of relief at being the only 'Value Carrier' (and only airline overall) providing Recliner J and (third party) lounge access on the PER-DPS route.
Had VA stuck to the rules of the application, I would've tipped that VA would've likely taken some of Batik's J loads on the PER-DPS route (and forgo Batik's third party J lounge access) even when VA provides no J lounge access at all for their own short-haul international services.
