Hi Jürgen,

I thought that we could present a list of available grids (e.g. from 
https://github.com/OSGeo/PROJ-data ) to the user where all grids are 
deactivated by default and the user could opt-in. Just like other 
software would offer e.g. a list of templates or similar.

Of course we don't know automatically what grids are of interest.
