I want to call out a behavior change in 1.12. PR #16765 <https://github.com/apache/iceberg/pull/16765> changed GeometryType / GeographyType so toString() always writes the resolved defaults instead of omitting them.
*Before*: Default instances collapsed to the bare type name. Geometry with no CRS printed geometry. Geography printed geography, geography(crs), or geography(crs, algorithm) depending on what was stored as unset. *After*: the constructor stores omitted CRS / algorithm as the Iceberg defaults, and toString() always includes them: - geometry → geometry(OGC:CRS84) - geography → geography(OGC:CRS84, spherical) *Implications* - Read path is backward compatible, as SchemaParser or Types.fromTypeName can parse the type string to the same Type object - Write path is not string stable. *Question*: Do we consider the type's `toString()` change a breaking change? Personally, I am okay with 1.12 moving forward with the changed behavior since read is compatible. But I wanted to bring this to the community attention.
