I think it was always intended as a crowding-relief exit.

There's going to be a new "Turnmill Street concourse", which amounts
to a new corridor connecting the current ticket office to the
interchange footbridge via the east side of the station, filling in
the gap between the station and the road. There will also be a
permanent new entrance, in exactly the same place as the temporary
one.

Thanks for the reminder Mr T. I've done some digging and the drawings are
available online via Islington's planning site, Case P081483, for anyone
interested. I don't think it's possible to link directly to pages within
online planning unfortunately.
