One needs to keep in mind that nothing comes free in this life. The following has been stated/inferred previously in the thread but needs to be keep in mind ..
(a) the Design Standards require that power need not be adjusted during the takeoff
(b) a flex takeoff is calculated with that level of thrust and a failure ought not to cause a great concern from the point of thrust considerations
(c) there is nothing to preclude a concerned pilot from increasing thrust following a failure. However, this adds to the handling problems and, depending on the aircraft/engine characteristics, may present you with a very significant problem. Quite some years ago I was involved in an accident investigation relating to a fatal in which the crew very likely were caught out by too much thrust asymmetry following a failure with quite confusing indications .. Vmca departure and no survivors.
While the need for thinking pilots will remain ... too much innovative thought can bite if it is not backed up by the appropriate level of manipulative skill and systems knowledge.
