Idk but i feel like the name Hydrator is not right here. It really feels more like a normalizer/denormalizer. Besides that 👍

[DavidBadura]

We already use the name "normalizer" to normalize individual values. And "hydrator" is a common name for transforming arrays into objects.

In any case, let's look at it again later to see if it can be structured better. I'm rebuilding the whole thing in several stages.
