Yes and no. It is used for the docblock of [setFile](https://github.com/UFOMelkor/VichUploaderBundle/blob/hotfix/Mapping/PropertyMapping.php#L80) and [getFile](https://github.com/UFOMelkor/VichUploaderBundle/blob/hotfix/Mapping/PropertyMapping.php#L67) (I'm not sure why it is not used as type hint).

If you prefer that I can add the FQCN to the docblock and remove the use statement.
