The 787 will do the same but it does not rely on data from the FADEC. It uses the IRS to detect the yaw. In fact, it will correct for anything that causes uncommanded yaw, not just engine failure.
It would seem the discussion has yawed away from a patent fault of some magnitude, a failing or failed generation system and a seemingly unsolved switching resolution. In an aircraft with a known history of failed generators, emergency landings and diversions, not to mention onboard fires, perhaps we are looking through a microscope at an elephant.
