True, there are ways to make this smaller, but if this is to be a GPKG a
spatialite Database should be avoided

With a Spatialite connection it is very easy to create an empty pure GPKG
Database (106.5 Kb) with:
It would contain only 3 SRS (-1,0 and 4326) in 'gpkg_spatial_ref_sys' with
all of the other GPKG admin-tables (including 'gpkg_extensions') empty.
