Wouldn't you have corrected for the error by the time you intercepted the
glideslope / localizer and use these nav aids for for shooting the
approach?

Even by using these, by the time you reach DH, you still should be in a
reasonable vicinity to hear the middle marker (if appropriate) to make a
missed approach decision based on your altimeter reading.
