Could be a LOT of stairs to climb.
Actually it's simpler. You're only going up and down, similiar to core servicing in a building.
With mezzanines and typical shallower stations, the route is more circuitous with at least 2 vertical movements compared to a single vertical movement. This makes it a lot easier for EMS and fire services to access the station.
It would be really advanteagous if the circulation building was more like an atrium in an office building or retail environment with direct opening to the sky above.
Another thing to consider is the use of high speed elevators as they have done in many othe rplaces around the world including the US where stations are much deeper.
