The middle button on the classic controller, what does it do?

I know if moves the back plating up and down, but what's the purpose is there some tool that works with it? It seems wierd Nintendo would add such a useless feature.

Not the home button for those who don't know what I'm talking about it's the button between the Zl and Zr buttons.

My guess would be a rumble pack?

Maybe it's actually a button for something in a vc game?
