Indeed I've mentioned this already. I'm not sure if this is part of that work however, since I thought the plans were for it to be more next year. On the other hand, what I've learnt about T5 is that because they can only work from 23 hrs to 04 hrs, and because the space is incredibly limited, it's possible they need this area as part of a process which eventually ends up with the new Emerald security area.
