Do you have some thoughts on how we are going to handle this in QGIS?
(Apart from that plan to download all grids on the first start :-))
My assumption was that QGIS would be shipped with no grids (simply too
much data to ship in installers), and if there would be a
transformation available with a missing grid, QGIS would show a
warning and let user download such a grid file with one click? Or did
you have something else in mind?
