I think that it is just another small feature in Lion that shows Apple is moving more mainstream. I think they are trying to hook new users and changing terms like "airport" to a more recognizable "wi-fi" is one way to make the transition easier.
Lion still offers Airport Utility for their own devices. However, looks like they have removed just the name "AirPort" for wi-fi access. I agree, stick with Airport or remove it altogether.

I think the idea is that AirPort will be used only when referring specifically to the AirPort Base Station while Wi-Fi will be used for any wifi connection. AirPort Utility configures the AirPort Base Station so it doesn't make sense to change that.
