This is specified here: http://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#lower-boundary-encapsulation

The key is that if the element is inactive, it should act as any HTML element: be stylable and show its contents.

A good example of why this is good is http://dglazkov.github.com/Web-Components-Polyfill/news.html, which is a component definition (used here: http://dglazkov.github.com/Web-Components-Polyfill/).

I added a special debug.css, which helps understand the structure of the component. If <content> were visible, I could style it and put "CONTENTS GO HERE" label with a selector or something.

That's instant debugging for a component developer :)
