Even,

My intention is that OGRSFDriver would go away and
OGR drivers would be registered with GDALDriverManager
the same way GDAL drivers are.  This would go along with
changes to OGRDataSource, possibly making it a subclass
of GDALDataset or perhaps a new super class of GDALDataset.

Well, my thinking on this is all still half baked, but the goal is
that OGR will have all the benefits of GDAL's metadata and
driver manager and I even dream of being able ot have one
dataset object with raster bands and vector layers for
things like a PCIDSK file.

Of course there will be some disruption - I think particularly
on the OGR side which is why I have waited for 2.0.

I hope to prepare some sort of roadmap for this in coming
weeks.

Best regards,
