This is possible but it is more work to remove the gettext infrastructure
for this Gnulib import. It would be possible that that Gnulib modules
we use could use translated strings in the future or that we use other
modules that do.
It should be harmless to have empty translations files as they do
not use much disk space and only occupy space on a directory listing.
Users of Gnulib translations in this situation are likely to miss that
the .pot file are not being updated and continue distributing irrelevant
and out-of-date translations.

My understanding is that packages do not provide these files to translators
and that the translations are updated from Gnulib translations by
gnulib-import.
For these reasons, a new method was designed and is now recommended.
If you pass the ‘--po-base=DIRECTORY’ and ‘--po-domain=DOMAIN’ options
to ‘gnulib-tool’, then ‘gnulib-tool’ will create a separate directory
with its own ‘POTFILES.in’, and fetch current translations directly from
the Translation Project (using ‘rsync’ or ‘wget’, whichever is
available).
(Info node (gnulib)Localization.)
Admittedly, I don't know how these Gnulib translations are updated, so it
is possible there is some knock-on effect. It depends if the Gnulib
project uses gnulib-tool somehow in providing strings to translators.
