Judgement: Adopt
Canonical catalog API for Iceberg; multi-vendor implementations.
Open REST API specification for Iceberg metadata catalogs. Decouples engines (Spark, Trino, Snowflake, Dremio, ...) from the catalog backend.
Together with Iceberg the table format, this is what is making "open lakehouse" something more than marketing.
