SpatialLite columns are actually quite a bit more interesting than this - they also have a geometry_type (point, polygon, linestring etc), a coord_dimension (usually 2 but can be higher) and an srid.

For example:

The SRID here is particularly interesting, because it helps hint at the fact that the results from these queries won't be latitude/longitude co-ordinates - which means that AsGeoJSON() won't return results that can be easily rendered by Leaflet:

Compare with https://timezones-api.now.sh/timezones-a99b2e3/geometry_columns:
