And if you are interested on encoding Geospatial Data there is a format called Geoparquet that is on the way of standarization: https://geoparquet.org/ Essentially adding metadata on the extensible schema metadata streucture that parquet supports. Think of WKB in a column. With more exciting stuff coming that way.
Main issue with geoparquet at the moment is theres no spatial indexing. When that comes it becomes a lot more viable to replace both other GIS file types like geopackage and also for some cases even database storage like postgis.
Very much looking forward to it though, hoping it covers pointcloud and TIN data well eventually also
