Indeed. And given they will be having numerous other exceptional items this year, financially, writing off the value of the A380 fleet by permanently grounding them would be relatively attractive given the focus is on cash and on containing operating costs.
The implications for passengers though - no more F. Would be an issue if Frequent Flyers and large corporates planned to resume pre Covid travel habits however I would think in the medium term the lack of F wont be an issue - QF always said it had value, although they never explicitly said it had financial value. In the new world, I doubt the lack of F matters given the larger efficiencies.
(at least until Sunrise happens!)
