Ok you are right. I'm already using a custom `GetSetMethodNormalizer` which does the same thing on my codebase and I thought this would benefit to the community O:-)

Can you point me to a class that does this in the Form component ? I've seen the `DataMapperInterface` but I found not concrete implementation.  

The thing is, I'm not using forms at all, this is why it would not make much sense to use this component to do what I want to do.
