There are multiple incidents that were avoided becoming accidents when resting crew/supernumerary crew/able bodies (travelling crew) were able to help up front (eg. Sioux City). some airlines want their seat position as to be able to identify them. Smart move.
EK decided to go the other way, to dump them as far away from the cockpit as possible, even when it means doing this with the only Captain on board. Silly move.
I go with the remark that it dazzles me that regulators worldwide just swallow this uneccessary move.
