All I would add is in my interpretation:
there won’t be an indefinite stand down for a fleet. This is because the stand down (as opposed to other methods of managing a surplus) applies while the aircraft don’t fly. So For example, if the A380 never flew again the stand down could only apply for as long as the a380s were still parked and operational in QF colours. As soon as they were sold or discarded a RIN must occur and the stand down ends. I doubt QF would keep an aircraft just to avoid redundancy payouts.
It explains the lack of announcements regarding the 747, when everyone knows it has almost no chance of further operations. At the very least the waters are very muddy on this issue.
