KC built KCI for TWA and to there recommendation. TWA at the time was based in KC with over 10,000 employees. KCI was a total innovation and won awards from around the world. When hijackings started occurring TWA wanted millions of dollars in renovations done which the city could not afford. Thus TWA moved its hub based to St Louis. DFW's designed was based on KCI/MCI's. KCI's security lines are never more than 5-10 minutes long, so it's no big deal. The city would build a new airport if they had the money, the have long realized that KCI is a white elephant. But like everyone else, the city doesn't have the money to rebuild it. There's 90 gates, 30 gates per terminal. What the city should do is make one central checkpoint per terminal, but that could be hard to do because the total depth of the terminals is just 75 feet wide.
