TBD:

• Check pydantic's custom serializer to replace json_encoders in the BaseConfig definition.
• Wait for autodoc_pydantic's new support or use alternative for the Sphinx docs

• Also resolve autodoc_pydantic/directives/autodocumenters.py:137: RemovedInSphinx80Warning: The tuple interface of ObjectMember is deprecated. Use (obj.__name__, obj.object) instead.

• Try to have better definition for Time Intervals
• Look into unifying the astropy Quantity types
• Usage of Gammapy Metadata and other new features as per the Release Notes
• Revisit changes made in Add temporary function to get pivot_energy from a spectral model #160
• Revisit the changes made in Correct the calculation of Goodness of Fit stats #132

It is better to update the validation and serialization effort on the usage of the new pydantic dependency in a separate PR.
