there is also no justification of "access=no" for this: https://www.openstreetmap.org/changeset/161760953
(generally, you can just walk from the station along the fence of the hotel up to Viale Enrico di Nicola, there are not restrictions at all).
I do not recall 100% if the taxi access is physically connected to the square in front of the buses, but I believe it is (e.g. police can drive there).
