FOSRestBundle how to make it work with symfony/serializer?

Question

symfony

serializationGroups not working.
Controller:

/**
     * @Route("/", name="homepage")
     * @FOS\View(serializerGroups={"registration"})
     */
    public function indexAction()
    {
        return $this->get('app.user_repository')->findAll();
    }

Mistake:

Attempted to load class \"SerializationContext\" from namespace \"JMS\\Serializer\".\nDid you forget a \"use\" statement for another namespace?

It is clear that he uses the SerializationContext from JMS\Serializezr, but it is not clear why he does not use the standard serializer.

TL;DR
symfony/serializer started supporting serialization groups only from version 2.7, before that only jms serializer could do this. Therefore, fosrest simply does not yet know how to use symfony / serializer for these purposes. Alas, adding full support for symfony/serializer will lead to rather sad BC-breaks and we will only see its full support in FOSRestBundle 2.0.
