Looks like game over for ex-CAI:
The chosen departure city requires Royal Air Maroc to operate your first flight. Please choose a different departure city as Royal Air Maroc is not permitted to operate the first flight. Alternatively, please contact Royal Air Maroc directly to book your Round The World fare.
Attempting different first segments yields similar messages, sometimes with Qatar in place or Air Maroc.
On EF the fare is still alive but on fewer airlines than before - QF in particular is gone. Likely to be pulled completely sooner than later.
