Neither has there been any response regarding my request to include it in 2.02. I'd really appreciate some kind of comment.

Looks good to me. Thanks for doing the work! I think that maybe it is worth trying to include this in 2.02 release. If you wish please ask about that in this http://lists.gnu.org/archive/html/grub-devel/2016-03/msg00047.html thread. CC me if you do that.
