On the condition of the bodies:
The BEA report only references the 30 bodies recovered by the French frigate Ventose. The other 20 bodies were recovered by the Brazilian Navy, and the initial body recoveries were by the Brazilian Navy.
The BEA characterizes the bodies recovered by the Ventose as "clothed and relatively well preserved." There is no characterization of the bodies recovered by the Brazilian Navy.
There is a possible undertone of frustration with the Brazilian authorities with respect to the bodies. Early on, the French complained about being excluded from the team performing the autopsies. The BEA report hints that the French are still in the dark, stating that the Brazilian authorities have yet to provide any autopsy results. (Some bodies have already been released to families for burial.)
The BEA report contains no information on how many of the bodies, well-preserved or not, are already identified. Once identified, passengers can be matched with assigned seats, and this can be a valuable data-point with respect to how the plane impacted.
And then there is the damage done to the VS by the Brazilians in the course of recovering it....
