MCI was built back in the early 70s, way before the days of TSA and a "secure" area. It was designed to get you quickly from curbside to gate. With security now, the concessions are left out of the secure area.
Edit: OP, security has always been quick for me at MCI. You could spend your time outside security hydrating and pass through security when boarding begins.
