Another option might be not to search for the grids in any particular
directory, but to rely on a user-provided full path to the grid file in
the PROJ_INFO.

cs2cs, gdalwarp etc. allow the "nadgrids" to be a full path to a grid file.

To me this sounds quite reasonable.

Please add this suggestion to the ticket
