Note if `edges` is `"spherical"` then it is RECOMMENDED that `orientation` is always ensured to be `"counterclockwise"`. If it is not set, it is not clear how polygons should be interpreted within spherical coordinate systems, which can lead to major analytical errors if interpreted incorrectly. In this case, software will typically interpret the rings of a polygon such that it encloses at most half of the sphere (i.e. the smallest polygon of both ways it could be interpreted). But the specification itself does not make any guarantee about this.

If an implementation only has support for a single edge interpretation (e.g.,
a library with only planar edge support), an column with a different edge type
a library with only planar edge support), a column with a different edge type
may be imported without loosing information if the geometries in the column
do not contain edges (i.e., the column only contains points or empty geometries).
For columns that contain edges, the error introduced by ignoring the original
