Feature: #83092 - Replace @transient with @TYPO3\CMS\Extbase\Annotation\ORM\Transient 

Description 

As a successor to the @transient annotation, the doctrine annotation @TYPO3\CMS\Extbase\Annotation\ORM\Transient has been introduced.

Example:

/**
 * @TYPO3\CMS\Extbase\Annotation\ORM\Transient
 */
public $property;

Doctrine annotations are actual defined classes, therefore you can also use the annotation with a use statement.

Example:

use TYPO3\CMS\Extbase\Annotation\ORM\Transient;

/**
 * @Transient
 */
public $property;

Used annotations can also be aliased which the core will most likely be using a lot in the future.

Example:

use TYPO3\CMS\Extbase\Annotation as Extbase;

/**
 * @Extbase\ORM\Transient
 */
public $property;

Impact 

In 9.x there is no actual impact. Both the simple @transient and @TYPO3\CMS\Extbase\Annotation\ORM\Transient can be used side by side. However, @transient is deprecated in 9.x and will be removed in version 10.
