The grids in proj-datumgrid are used in the proj testsuite, hence
unpacking the content of that archive into the nad/ directory of the
proj source as packagers have done for many years is still highly
recommended.

The grids from proj-datumgrid are optional for the proj build, though.
Since proj 4.9 the build system was updated to no longer fail if the
grids are not present, allowing the grids to be unpackaged into
/usr/share/proj after installation (using a separate package for example).

The proj-datumgrid RCs were published after the proj RCs, this still
needs to be reflected in the proj documentation.

You should at least include this as its the successor of the previous
proj-datumgrid-1.5 & 1.6 releases, which packagers have included in proj
for many years.

There are optional. Ideally they are packaged separately to allow users
in those regions to easily install those grids.

Personally I'm not going to package those releases for Debian until
users actually request packages for those.

Docs are still a work in progress, see:
