Thanks for your submission.

Note that you need not create a new thread for to send a update of a
patch.  If you used the `git send-email` command, you could have used
the `--to=` option to send to the previous thread.  For instance

git send-email --to=39756@debbugs.gnu.org 0001-my-patch.diff
--8<---------------cut here---------------end--------------->8---

I think you don't need to copy the whole package definition.  Instead,
you could `inherit' from the original definition and only adjust the
name, description, inputs and maybe arguments.

For instance

--8<---------------cut here---------------start------------->8---
(define-public emacs-exwm-next
  (package
    (inherit emacs)
    (name "emacs-exwm-next")
    (inputs ...)
    (synopsys ...)))
--8<---------------cut here---------------end--------------->8---

See `substitute-keyword-arguments' in the fftwf package for a convenient
way to modify just one argument.

> +    (synopsis "Emacs X window manager")

Maybe tell that this is using the next version of Emacs.

Shouldn't this be `emacs-next` as well?

Cheers!
