I probably added this information to the non-free section a decade
ago, back when it was on a Trac wiki. As the instructions note, at the
time you had to get a special log in to get the files. But now that it
has a more appealing license and no registration, it seems that these
files can be included for general distribution.

I've started a ticket here: https://github.com/OSGeo/proj-datumgrid/issues/26
