We need to introduce a mechanism where users can switch on and off dynamic download of PROJ-related data. Depending on the available internet connection (none, too slow, too expensive), automated download might need to be disabled, in which case we need to introduce warnings that PROJ-related data are missing for certain coordinate operations.

Re: [GRASS-dev] GRASS GIS ready for PROJ 7?
To underpin Jürgens point: In my company we used "creatensis.pl" to create custom OSGeo4W installations with modified startup scripts (so users get prepared configurations. That worked quite well. Doing so for a "GRASS GIS standalone" installer might reduce maintenance, risk of bugs and confusion among users. So, I would definitely recommend to follow Jürgens suggestion.

The standalone installer of QGIS is directly based on OSGeo4W packages. It just starts off with the qgis-full package and includes all it's dependencies and hence also includes GRASS. The packages are fetched and extracted and packed up again for the installer, which later runs extracts them on and runs the included postinstall scripts of the OSGeo4W packages on the target machine. Except for selecting the target directory and setting whether desktop and/or start menu shortcuts should be created, there is currently no way to add more configuration. The same approach, but starting off with grass instead of qgis-full could also work for GRASS. And creatensis.pl was ported to MSI as createmsi.pl - because it now uses the Microsoft Installer instead of NSIS to work around NSIS' 2GB limit. The experimental MSI installer also includes GRASS (although not the latest updates of OSGeo4W regarding os.add_dll_directory necessary for Python 3.9).
