I had intended to and still may well. But today's experience allowed me to share yesterday's with the CSM.
I again flew out of Sydney, this time on a widebody but out of gate three. To backtrack slightly, on arriving into Sydney off another flight I noticed four QF staff standing around at the entrance to what I call the rotunda, near gates 12-15 or so. I recalled one or two people here mentioning staff had been monitoring implementation so I hung back a couple of minutes and watched them to see if this was the team. I walked up, politely interrupted and asked if they were checking the rollout. They were but, dammit, one of the people I was speaking to was the same supervisor who I'd spoken to the day before. I'm sure he recognised me as I certainly recognised him. So I just quickly asked how it was supposed to work and the same guy said FAs are supposed to board the premium lane first before boarding the non-premium.
A little while later I left the lounge to board my flight, again with a little note to leave the gate staff thanking them for the changes in hope that today it would be needed. It was. Premium boarding was announced and that lane was boarded while the non-premium was not. Both scanners were being used (and remember, this was gate three where there's only one door). I left the thank you note with the gate agent who scanned me. After the meal service the CSM stopped by to thank me for the note and asked for my feedback. I politely unloaded. He was very sympathetic - genuinely so, I believe. I showed him the thank you note from the day prior that wasn't needed that I had in my pocket, complete with the name of the guy behind the desk who couldn't have been less interested. He shared my disappointment. He really seemed to be interested in what I had to say, giving me probably 10 minutes of his time. He said he'd provide the feedback to Qantas and I believe that he will.
My understanding is that's how it's supposed to work: board premium first and when that line is exhausted, move to non-premium. However, if a premium passenger arrives later, he or she should be boarded immediately.
