I don't see any problems in including these on both the website and the European datumgrid package.
The simplest way to make this happen is to submit pull requests to the PROJ and proj-datumgrid
repositories on GitHub.

Emne: [Proj] NTv2 grid between Belgian Datum 72 and ETRS89
Hi Proj community,
I'm the author of a NTV2 grid to convert Belgian Datum 72 to ETRS89.
This grid increases the accuracy of the convertion between Belgian Lambert 72 (EPSG 31370) and Belgian Lambert 2008 (EPSG 3812).
It has been validated by Service Public de Wallonie (SPW) and Institut géographique National (IGN) as you can see on http://www.ngi.be/FR/FR2-1-7.shtm
My request is, can you include a link in https://proj4.org/resource_files.html for Belgium with somethings like that
Belgium Datum 72 to ETRS89

I'll be glad if the grid can be included in the proj-datumgrid/europe/ package
I am open to any form of communication to make this information known.
Let me know.
