However, it becomes necessary for autovalidation to work with such entities, so it should be in 4.3:```php/** *@entity */class Foo{    /**     *@id     * @GeneratedValue(strategy="AUTO")     *@column(type="integer")     */    public $id;}```Commits-------4598235 [Doctrine][PropertyInfo] Detect if the ID is writeable
