Suppose we could just remove the assertion in `BasicUPgradeFinalizer` and let any client fetch the status of finalization? I'm not sure whether it will cause any problems? If we add an extra flag `readonly` here, it just want to allow to return status to any client, which seems to be overlapped with part of the meaning of `takeover`. -- This is an automated message from the Apache Git Service.
