Description: 

Plugin types that use annotations for discovery can provide an attribute class since Drupal 10.2.

Not providing an attribute class is now deprecated, and an attribute class will be required in Drupal 12.0. It is and will still be possible to also provide an annotation class for BC until Drupal 13, only then will support for annotations be removed completely.

See Plugin types should use PHP attributes instead of annotations and Plugin implementations should use PHP attributes instead of annotations for more information.
