In the last twenty years, there are just two cases of lost-at-sea I can think of in which evidence from the hull was *not* required in addition to FDR data to determine cause. There are five cases in which in-air disintegration or burning, which are not identifiable from FDR data, initiated the hull loss, and there is one further case in which physical evidence was required to show there was no anomaly (that it was, in effect, murder/suicide). Two against six isn't a persuasive ratio.

I can go through the records to make this definitive rather than "I can think of", if necessary.

The result of a cost-benefit analysis, even for the past, let alone for conceivable future cases, is not at all evident to me.
