Personally, despite being P1, I feel this is poor choice by QF. I also wouldn't be too surprised if they back down, at least on WP. That would be sensible.
I also do not understand why they would not do this in smarter way. If they insist on enabling this for those with status on hundreds more flights a day, then why not create a tierred pricing approach? Broze $x, Silver 75% of $x, Gold 50% of $x, etc.. I mean if you must do it, show there are real benefits the higher up you go. P1 is a step too high for the vast vast vast majority of flyers, and CL impossible to earn, but WP is not unreasonable - specially to many here.
If you're going to charge Plats, make it nominal.. 25% of $x or ideally keep it free, or maybe even say "Look if at T-80 or when you check in the exits are free, you can move free of charge" which would still give a chance to those not willing to pay
I think there are ways to go about this tho satisfy their revenue urge but to also make it more customer friendly(as much as you can !)
Still, I think robust feedback to QF may get them to reconsider, as VA did....
