I did not review the concept but I did review the copying of ResourceRequest objects.

> Source/WebCore/loader/PolicyCallback.h:56
> +    void setRequest(ResourceRequest& newRequest) { m_request = newRequest; }

I think this should either take a ResourceRequest&& and use WTFMove, or it should take a const ResourceRequest& and always copy. Taking a non-const reference and copying does not seem right.

> Source/WebCore/loader/PolicyChecker.cpp:151
> +        continueAfterNavigationPolicy(action, newRequest);

I think that WTFMove here would avoid copying the ResourceRequest.

> Source/WebCore/loader/PolicyChecker.cpp:222
> +                callback.setRequest(*newRequest);

I think that WTFMove here would allow us to avoid copying the entire ResourceRequest.

> Source/WebKit/WebProcess/WebCoreSupport/WebFrameLoaderClient.cpp:834
> +        newRequest = navigationDecision.newRequest;

Using WTFMove here we could avoid copying the ResourceRequest.

> Source/WebKit/WebProcess/WebPage/WebFrame.cpp:256
> +    function(action, newRequest);

Adding WTFMove here would avoid copying the ResourceRequest.

I think PolicyCallback should be removed and replaced by WTF::Function and lambdas, but not in this patch.

We're not needing this any more
