Hi Christopher, Alex Kost wrote in the past that they no longer want to be involved.
As you know, the “official” repo is now at <https://git.savannah.gnu.org/git/guix/emacs-guix.git>. If you would like to give a hand or take over maintenance, you’ve very much welcome to do so: it’s a great piece of software and it’s sad to see it bitrot. For now, you can send patches to guix-patc...@gnu.org with “Emacs-Guix” in the subject and I and other committers would be happy to apply them. Thanks for offering to help! Ludo’.
