Again in the first thread someone with access to a commercial 77 flight simulator attempted to see what would happen with both engines out. The aircraft does not go into "
an uncontrolled high speed descent exceeding VMO/MMO" it flies a phugoid - speed increases then the nose comes up then speed decreases till the nose goes down etc. Of course it could be manually put into a high speed descent exceeding VMO/MMO, however, contrary to your idea this would have resulted in a large amount of floating debris as the airframe would break into thousands of pieces on impact with the surface. Much of that debris would float as was the case with AFR447.
Note that finding debris only a few days later did not assist the search for the main fuselage of AFR447, so finding something from MH370 a year later only closes down the more wild tin-foil-hat hypotheses and embarrasses some authors.
