API Platform: associate many resources to a same entity

I would like to create 2 different resources App\Resource\Category et App\Resource\Classification, which would be associated to a same entity App\Entity\Classification. We have 2 different endpoints v1/classifications and v2/categories. I would have liked that both ressources extend the same entity.

Pseudo-code example:

<?php
// src/Entity/Classification.php
namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="App\Repository\ClassificationRepository")
 */
class Classification
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $code;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $label;

    /**
     * @ORM\OneToMany(targetEntity="App\Entity\ClassificationAttribute", mappedBy="classification")
     */
    private $classificationAttributes;

    public function __construct()
    {
        $this->classificationAttributes = new ArrayCollection();
    }

    public function getId()
    {
        return $this->id;
    }

    // ... getter and setter methods
}

<?php
// src/Resource/Classification.php
namespace App\Resource;

use ApiPlatform\Core\Annotation\ApiResource;
use App\Entity\Classification as ClassificationEntity;

/**
 * ...
 * @ApiResource(
 *     collectionOperations={"get"},
 *     itemOperations={"get"}
 * )
 */
class Classification extends ClassificationEntity
{
    // ...
}

<?php
// src/Resource/Category.php
namespace App\Resource;

use ApiPlatform\Core\Annotation\ApiResource;
use App\Entity\Classification as ClassificationEntity;

/**
 * ...
 * @ApiResource(
 *     collectionOperations={"get"},
 *     itemOperations={"get"}
 * )
 */
class Category extends ClassificationEntity
{
    // ...
}

and each resource would have its endpoint, its serializer, its normaliser, etc, etc, ... To summarize, each resource would be customized its own way.

Except there is no possibility to use annotations et inheritance at the same time: annotations of the extended entity are not used.

I could associate a distinct DataProvider to each resource, and plug these DataProviders on the repository. But doing that, I lose every native fonctionality of the Doctrine ORM Extension and have to reimplement every one I use (an example among many: @ApiFilter)

Is there a simpler way to associate many resources to a same entity?

Thank you for your help.
