That's exactly what I was getting at... I don't like the idea of plopping concessions right in the center aisle of the concourse, which I noticed that they're already starting to do that last time I was out there.  Plus, if they do add extensions onto the end of the existing concourses to make them longer, they need that center space for additional walking escalators.  

Just a side note on #2... the most extreme example of that boom-bust timing I've seen is at the Reyjavik airport. They cluster a TON of flights together into the morning slot (like 6am-8am) because of redeye flights going from the US connecting on to mainland Europe.  We had like 5 flights departing on our end of the concourse within half an hour, with people standing in line to board criss-crossing other flights boarding.  You had to be really careful to make sure you entered the right jetway because it would have been so easy to get sucked into the wrong one.  It was a mess.
