How exactly does an installer that can write to any location on your disk fit into a restricted AppStore?

Also, does this mean I'm free to distribute my malware installer through the AppStore? After all, it's just an installer.

Can anybody else distribute a foo installer, so normal restrictions would not apply?

Nope. Xcode is special.

Cool! Does this mean I will be allowed to distribute App Install scripts through the AppStore? The best of both worlds: free distribution & full control!
