question: boolean maySendBasePageUrl ( ) { return ! isUserUndecided ( ) ; }
target:  Whether sending the URL of the base page to the server may be done for policy reasons. NOTE: There may be additional privacy reasons why the base page URL should not be sent. TODO(donnd): Update this API to definitively determine if it's OK to send the URL, by merging the checks in the native contextual_search_delegate here.
