A GeoPackage is just a SQLite database with an OGC schema - you can run SQL against it right now. We tested the field-name truncation, the Latin-1 encoding trap and the NULL collapse that Shapefile inflicts, plus the ogr2ogr commands that fix them.
Collect and edit in GeoPackage, publish to the web in GeoJSON, send a Shapefile only when the other side insists. The evidence: the IBGE 27-state mesh converted three ways and measured on eight criteria, from bytes loose and zipped to the .cpg encoding trap, the EPSG code and viewer load time.
