Are you using this? Is it by chance supposed to be
content/public/common/referrer.h?

ah yes! i'd just blindly copied it from the old file w/o noticing. :)

+#include "chrome/browser/profiles/profile.h"
+#include "chrome/common/pref_names.h"
+#include "content/public/browser/web_contents.h"
+
+using content::OpenURLParams;

optional nit: I've been told to only use `using` when it really significantly
improves readability, but I can't find a reference for that, plus this was
pre-existing code, so, *shrug*

Done.

+using content::Referrer;
+
+ChromeControllerClient::ChromeControllerClient(
+    content::WebContents* web_contents)
+    : web_contents_(web_contents) {}
+
+ChromeControllerClient::~ChromeControllerClient() {}
+
+void ChromeControllerClient::OpenUrlInCurrentTab(const GURL& url) {
+  OpenURLParams params(url, Referrer(), CURRENT_TAB, ui::PAGE_TRANSITION_LINK,
+                       false);
+  web_contents_->OpenURL(params);
+}
+
+const std::string& ChromeControllerClient::GetApplicationLocale() {
+  return g_browser_process->GetApplicationLocale();
+}
+
+PrefService* ChromeControllerClient::GetPrefService() {
+  Profile* profile =
+      Profile::FromBrowserContext(web_contents_->GetBrowserContext());
+  return profile->GetPrefs();
+}
+
+const std::string ChromeControllerClient::GetExtendedReportingPrefName() {
+  return prefs::kSafeBrowsingExtendedReportingEnabled;
