[PROJ] request for integration of optimized transformatiegrid BD72 to ETRS89

[Praet Karin]

Hi,

The Belgian National Institute of Geography (NGI) has published a more accurate transformationgrid to convert between Belgian Datum 1972 tot ETRS 89.
As Belgian Lambert 1972 (EPSG:31370), based on BD72,  is widely used in Belgium - is it possible to integrate this transformationgrid as the default transformation for this datum?

Documentation in Dutch:  http://www.ngi.be/NL/NL2-1-7.shtm
Documentation in French: http://www.ngi.be/FR/FR2-1-7.shtm

The grid is called: bd72lb72_etrs89lb08.gsb
