Yes! Alex, thanks a lot for taking care of the last pending change of #18507 👏

Bit late to the party but am I missing something (have not tried 7.0) but this example would not work? Looking at the serializer class in 7.0 it seems nothing has changed about its behavior.
https://github.com/symfony/symfony/blob/8105a092b16a10d704f0e64b1194f0d0ea0234b3/src/Symfony/Component/Serializer/Serializer.php#L92-L94

You mention it yourself in #18779. But then using NormalizerAwareInterface/NormalizerAwareTrait would still set the Serializer class instance for the normalizer property resulting in the custom normalizer supporting $data recursively being called when you manually call $this->normalizer->normalize($data) in the normalize function.

I could not find anything about a PR that changes this to work well in 7.0 so should this be in here? At the least it should be a valid example with a "workaround" not?
