Now deprecated Conversion Library has support for type-relaxed conversion plus a way to insert custom conversion code. New toEntity/toValue support in UnitOfWork don't.
- don't expose the whole state (eg. password hashes)
- computed/transformed state (eg. entity state ~ value state)
This issue is about finding additional solutions to support theses usecases in the toEntity/toValue mechanism.
