Hello,

I am curious by what standard do the binaries at 
<https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal> have a "fairly 
minimal sets of drivers"?

Iterating over ogr.GetDriver() for the 3.0.4 binaries returns:

ARCGEN, AVCBin, AVCE00, AeronavFAA, AmigoCloud, BNA, CAD, CSV, CSW, 
Carto, Cloudant, CouchDB, DB2ODBC, DGN, DXF, EDIGEO, EEDA, ESRI 
Shapefile, ESRIJSON, ElasticSearch, GFT, GML, GPKG, GPSBabel, 
GPSTrackMaker, GPX, GeoJSON, GeoJSONSeq, GeoRSS, Geoconcept, Geomedia, 
HTF, HTTP, Idrisi, JML, JP2OpenJPEG, JPEG2000, KML, LIBKML, MBTiles, 
MSSQLSpatial, MVT, MapInfo File, Memory, NGW, ODBC, ODS, OGR_GMT, 
OGR_PDS, OGR_SDTS, OGR_VRT, OSM, OpenAir, OpenFileGDB, PCIDSK, PDF, 
PDS4, PGDUMP, PGeo, PLSCENES, PostgreSQL, REC, S57, SEGUKOOA, SEGY, 
SQLite, SUA, SVG, SXF, Selafin, TIGER, TopoJSON, UK .NTF, VDV, VFK, 
WAsP, WFS, WFS3, Walk, XLS, XLSX, XPlane, netCDF

Some drivers (e.g. JPEG LS) and features (12-bit JPEG in TIFF) are 
disabled because of library conflict, build, or stability issues.

Excluding drivers depending on GPL (e.g. Poppler, MySQL) or proprietary 
licensed libraries, what commonly used drivers are missing?

Everything except for the LGPLed GEOS library is statically linked. The 
wheels include the GDAL tools, link library, and include files.

I am not working in the geo/GIS field and am not using GDAL regularly, 
so I might be missing something.

I sent my nmake.opt and patch to the to swig/python package to Christoph 
Paulik.
