Review comment (refactor):
with the above `_ERROR_MAP` suggestion applied, we can simplify this:
```suggestion
        if status != 'public':
            if error := self._ERROR_MAP.get(status):
                raise ExtractorError(error, expected=True)
            self.report_warning('Falling back to webpage extraction')
            return None
```
