I guess that's unlikely they would add it to the binary packages, as it
would add a few MB to the base install.  But they might add it to
proj-datumgrid-1.5.zip (which contains many free datum files), as the
licence for the grid is BSD.

Makes me think - could QGIS ship with the freely available gsb grids, in an
optional package (say qgis-datum-grids)?  It would be rather convenient,
especially as QGIS now supports them (but does not ship with any grids yet,
unless mistaken).

cheers,
Etienne
