With regard to BEA's deciding not to have a Brazilian family group representative on board Ile de Sein during the recovery process, probably a good idea. One assumes there will be no rep for French or any other nationality family groups either; none would contribute to the job in hand and they could easily complicate things unnecessarily.
One also has to doubt Brazilian participation from here on in. The ports of Suape and Recife have been used as bases for the first stages of the search because they're the closest but, given the emotional content, the "Ile de Sein" continuing to use one of them while carrying wreckage and body evidence would be tempting all sorts of legal interference.
Better to base in Cape Verde if, in fact, more than one wreckage recovery sortie by the "Ile de Sein" proves necessary.
"Alucia", btw, appeared on AIS off Suape this morning but has since disappeared; she may have switched off. "Ile de Sein" continues to show fleetingly in the Canaries.
