That's why we need the DFDR/CVR to find out what the a/c actually did.
When Occam's rule is run over the outcome, none of what any of us have postulated may fit. For instance, all those that were found may have been unseated and standing, kneeling or in some other position at each end of the cabin. Now that could certainly be possible if the a/c was rotating about its longitudinal center of gravity in the so-called "deep stall".
Just another angle on it.
