I committed this patch, which activates the Python rewrite of gnulib-tool

soon.

It may be preferable to state the supported version directly,
and replace the above 6 lines with:

  if python3 -c 'import sys; sys.exit(not sys.version_info >= (3,7))' 
2>/dev/null; then

+      exec "$gnulib_dir/gnulib-tool.py" "$@"
+    else
+      echo "gnulib-tool: warning: python3 not found or too old, using the slow shell-based 
implementation" 1>&2
+      exec "$gnulib_dir/gnulib-tool.sh" "$@"
+    fi
+    ;;

I've updated to the latest gnulib now in coreutils,
and the auto python selection works well.

thanks!
