Still the temporary Thai lounge as of last week. I wasn't particularly impressed by my experience at Phuket airport with Qatar. There was chaos at check-in and no fast-track escort service. In contrast, my experience with Malaysia Airlines was much better. No queues at check-in, I was escorted through security and MH use the Coral lounge which, as you say, is much better than the Thai lounge. If I were travelling QR, I would try to minimise the amount of time spent at Phuket airport before departure.
