> The headline should read Google Chrome Skin

That would be redundant. Long before Google had a browser, the URL bar, buttons, scroll boxes, etc, of a browser (as opposed to the rendering engine) were called chrome.[1]

Developers didn't refer to browser skin, developers referred to browser chrome.

This is — quite literally in the original sense of the term — Google Chrome for the WebKit rendering engine.
