Further up this thread, Huck posted a
diagram of the relevant part of the airport.
Looking at this end of the terminal on Google Maps, it looks like all the lettered stands have been more recently grafted on to an existing terminal. Is that correct? Does their proximity to the taxiway and the shape of the area inside the "bowl" increase the likelihood that if something isn't right on the apron, an arriving aircraft will have to hold short at a position where it might not have completely cleared the taxiway?
I can't help wondering whether - if one is looking for holes in the cheese rather than trying to assign fault or cast blame - adding all these gates exactly where they are might not have been such a good idea, if their position increases the risk that an incident like this might occur.
