Too much speculation here.
LE or TE Asym or Disagree would incur speed and fuel burn restrictions/penalties and preclude a crossing.
Further failure would likely lead to a 'land at nearest suitable'.
Wiser to be turning back to a major hub with all the toys than pitching off into the unknown with your fingers crossed.
Pax safety trumps commercial considerations.
Correct decision by the crew. Well managed. Safe outcome.
End of.
