nothing to change here, but fwiw:

My distaste for the Value API means I would have just DCHECK(result &&
result->IsType(LIST)) then just static_cast<>'d within the OnResponseReceived
call.

+  const base::ListValue* result_list = NULL;
+  CHECK(result->GetAsList(&result_list));
+  context()->pepper_request_proxy()->OnResponseReceived(
+      request_id, true, *result_list, "");
