Thanks for sharing!

emacs-lucid closure size is 783.7 MiB.
emacs is 1181.3 MiB.

The difference really shines when building EXWM against emacs-lucid: it
makes for a much lighter Guix System.

Most Emacs packages don't have "emacs" in their closure.
So if we add emacs-lucid, one of the few extra packages we would have to
add beside it would be emacs-lucid-exwm (or emacs-exwm-lucid).

Thoughts?
