Whoever's bones have been unearthed that should be the end of the story unless still more bones are found in the vicinity. Whatever the case, no member of the Imperial family could possibly still be alive and the possibility that one or more escaped and lived clandestinely until death is only moot. As for the Russian Orthodox Church, it has its own agenda. I'd be more interested in what researchers can find in dusty, long-closed archives, record offices and private collections on the family, their fall from power and their murder.
