Having to walk for 10 minutes through the airport when your flight leaves in an hour isn't a big deal. However, it's a different story when you don't even want to be at the airport. At a lot of airports you can step out of a train, walk through the airport following a huge sign saying "BUSES THIS WAY", and step into a bus less than five minutes later. Having a short and well-signed intermodal connection is essential if you expect people to actually use it. Hiding it in an unmarked corner two walks and a people mover ride away isn't exactly what I would call convenient.
