I never got to go there but I don't see why they should remove the arrival hall (or any content) from the game.
Even if they wanted the island to be their new showcase starter experience, they could have kept it accessible from somewhere in RK to discover, or given you some kind of choice during character creation where you were sent, or if it didn't take too long let people go through the arrival hall AND the island, even if the arrival hall was just a quick walking through, and let you get some idea of where you were going on that ship. Maybe even let you get a tiny hint of the danger of the invasion in dialogue or with a glimpse through a window.
Just don't think they should have removed it, it's not like it was horribly broken was it? Or anything for them to be self conscious about. Storyline problems are easy enough to patch up am I right? You could think of 1000 reasons they could want to cross an ocean before dropping peeps off at bor/rome/oa.
