Extbase

PHPDoc Blocks with type hints mentioning Necessary for Extbase/Symfony.

Those are necessary (at least with TYPO3 v12) because of Extbase and the underlying Symfony component.

Extbase uses the PHPDocExtractor first, before using the ReflectionExtractor, both part of Symfony property-info package. The ReflectionExtractor will check the mutator followed by accessors prior checking the property itself. Some of our properties have different return values by accessors than the stored value that is set to the property. We therefore need to keep the PHPDoc block as this is checked first.
