Review Comment:
I think we're okay to skip the validation on the Pydantic side, we should
validate the input anyway to generate a more meaningful error.
We could set it to deep-copy using the `deep=True` kwarg. Doing this in
Pydantic is probably an order of magnitude more efficient than doing this in
Python.
