"Enforce required keys and enforce defaults" makes code needlessly cumbersome

[curieux]

Regarding the change issued here
https://github.com/developmentseed/geojson-pydantic/blob/main/CHANGELOG.md#060a0---2023-04-04

# Before
Feature(geometry=Point(coordinates=(0,0)))

# Now
Feature(
    type="Feature",
    geometry=Point(
        type="Point",
        coordinates=(0,0)
    ),
    properties=None,
)

This change is unfortunate for a few reasons:

• it violates semantic versioning, because the fundamental call has changed in an incompatible way without a major version change https://semver.org/
• it is incorrect to say that the old system did not follow the GeoJSON spec. The GeoJSON spec is about JSON, not about Python objects. As long as the @validator and .json() work correctly, GeoJSON is met.
• it is unpythonic to repeat identical information Feature(type='Feature", ...

We have been using geojson-pydantic for several projects, and have had to issue patches (or pin to <0.6.0) throughout.
