*document().frame() -> *frame

I think we can lose the m_frame.page() check here. I suspect it was just there due to pointer paranoia.

Ditto.

> -    m_focusedFrame = newFrame;
> +    if (oldFrame != &m_mainFrame)
> +        oldFrame->deref();

This could probably use a comment.

> Source/WebCore/page/FocusController.cpp:357
> +        document.setFocusedElement(0);

nullptr

> Source/WebCore/page/FocusController.cpp:429
> +// @param start The node from which to start searching. The node after this will be focused. May be null.

I know you are just moving them, but these comments sure look out-of-place in WebKit.

> Source/WebCore/page/FocusController.cpp:784
> +    Node* focusedNode = (m_focusedFrame && m_focusedFrame->document()) ? m_focusedFrame->document()->focusedElement() : 0;

Looks like this should be an Element*.

> Source/WebCore/page/FocusController.h:86
> +    Frame* m_focusedFrame;

Bug! This is missing from the constructor initializer list.

EWS looks sick, so I'm just dumping some comments for now:

> Source/WebCore/css/SelectorChecker.cpp:414
> +                Frame* frame = element->document().frame();
> +                return !frame || !frame->mainFrame().focus().isActive();

I wonder if we can really find ourselves matching selectors while Document is Frame-less.
isFrameFocused(Element*) in the same file seems to indicate that we could, but I'm not sure.
Our future selves can figure that out.

> Source/WebCore/page/Page.cpp:421
> +    if (!m_mainFrame)
> +        return;

This should not happen. m_mainFrame is initialized by the Page constructor and never cleared.

> Source/WebCore/page/Page.cpp:563
> +    if (!m_mainFrame)
> +        return false;

Same here.

Chris removed MainFrame so this idea doesn’t apply any more.
