While you may want that, you must ask yourself what do the people who are regulars of the Flounge want? I think if you spend the considerable change to buy an F ticket or in my case spend the countless hours on OneWorld flights to accumulate Platinum status, you don't want a lounge packed where there are queues just to get in the door never mind getting seated for dining. Don't think this can happen? Try visiting an airline lounge in America and you'll see first hand what the experience is like when airlines de value de experience of de lounge. At one airport I was at (LAX) the line for the Delta lounge stretched out the door and to the end of the TSA security line. And it's not just America too: a similar thing is happening with Air Canada lounges north of the border where they have separate queues for normal elites, super elites, and those travelling in paid J.
What I will say about this system is Qantas hasn't come out and given these passes away like lollipops. Frankly anyone with a beating heart can get access to the Air Canada or Delta lounge these days. For Qantas, aside from the one or two passes you get from a credit card, that's it. And one would hope that Qantas uses common sense to turn on and off that revenue spigot to optimize for passenger experience (rather than just the bottom line).
As for the international business lounge the big issue is they suck and IMHO aren't worthy of the designator international business lounge. The catering is very limited (at least that's my experience at the SYD lounge), some lounges are buried underground (i.e. MEL) and the seating quite frankly can't hold a candle up to domestic business lounges. They are in dire need of investment which is something Qantas has signalled. If they can rehabilitate these lounges to a suitable standard, I reckon few business class travellers would mind having to rough it out there.
