For many people premium economy seems to be a fantastic product. In theory I agree, but doesn't it all get down to price? I just looked at several dates SYD-LHR cheapest I could find was $4.6K (OK no sales on at the moment), and on some dates $5.6 and $6.2K. It's not too hard to find business class for around these prices (or a little more), admittedly not on Qantas. If I was going to pay $4.6K I'd be happy enough paying $5.5k to go in business if I could. I'm also still in the camp of 7hr economy +13 hr in flat seat business is better than 20hrs in premium economy, particularly if one can secure and exit row seat on the 7 hr economy sector.
