>+        There is a client that uses WKFramePolicyListenerUseWithPolicies to send website policies as
>+        a response to the WKPageNavigationClient's decidePolicyForNavigationResponse.  That is wasting
>+        effort to generate policies that don't change anything. Once that client adopts WKWebView
>+        they won't be able to do this any more, so temporarily remove the assertion.
>+        Also, make the assertion about process swapping a release assert to prevent that client
>+        from adopting WKFramePolicyListenerUseInNewProcessWithPolicies for navigation responses.
>+        It should only be used for navigation actions.
