I've updated both the RFC and the implementation (number of changes since the
preliminary one) to what I believe should be close to their final states.

In addition to the rather dummy example of a Python driver that is in the RFC,
there are 2 more interesting examples:

* a PASSTHROUGH driver that forwards calls to the GDAL SWIG Python API:
  https://github.com/rouault/gdal/blob/pythondrivers/gdal/examples/pydrivers/ogr_PASSTHROUGH.py

* a driver implemented a simple parsing of CityJSON (https://www.cityjson.org/)
  https://github.com/rouault/gdal/blob/pythondrivers/gdal/examples/pydrivers/ogr_CityJSON.py

The tutorialshould also help:
https://github.com/rouault/gdal/blob/pythondrivers/gdal/doc/source/tutorials/vector_python_driver.rst

I'll submit the RFC to vote soon if there are no other remarks.
