      SERVER-78470 introduced this condition to skip restoring children stages when Update/DeleteStages are already EOF. This appears to have caused a significant performance regression on some workloads.

      Performance patches have shown that restoring children unconditionally but allowing failures to restore in the cases where it is not necessary resolves the performance regression, while keeping the same semantics required for SERVER-78470.
