Description (last modified by )
The josm Debian packages depends on proj-data for the grid files it provides (#14422).
With the release of PROJ 7.0.0 scheduled for March 2020, the proj-datumgrid repository which serves as upstream for the grids is deprecated in favor of the proj-data repo containing the grids in GeoTIFF format and who are provided by the new CDN. See PROJ RFC 4: Remote access to grids and GeoTIFF grids for details.
JOSM should probably add support for the CDN to fetch grids on demand when it needs them and they're not locally available.

CDN is live: https://cdn.proj.org/
File format is specified here: https://proj.org/specifications/geodetictiffgrids.html#geodetictiffgrids
Thanks for the info! I have updated #2372 in order to support GeoTIFF first.
