 Each row is a storage format version: what a `spatialdata` release writes, and the version of the
 abstract data model it encodes.

 Storage format 0.3 is written by `spatialdata` 0.4.0 – 0.5.x and, on request, by `spatialdata`
 0.6.0 and later. Both write the same container, element, Zarr and NGFF versions; stores written by
