I do applaud this kind of work. Better, faster tooling for data as files and moving across runtimes is sorely needed.
Two things I would hope to see before I'd start using Vorter is geospatial data support (there's already Geoparquet [1]) and WASM for in-browser Arrow processing. Things like Lonboard [2] and Observable framework [3] rely on Parquet, Arrow and Duckdb files for their powerful data analytics and visualisation.
