Parquet + Arrow hopefully seem to be emerging as standards. I would much rather see those standards improved than new formats emerge. Even within those existing formats there has become enough variation than some platforms only support a subset of functionality. That and the performance and size of the libraries is poor. e.g. DuckDB / Clickhouse Parquet nanosecond compatibility. https://github.com/duckdb/duckdb/issues/9852 https://github.com/duckdb/duckdb/issues/9852 e.g. The arrow SQL driver is 70+MB in java.
