In the same spirit, I have:

--8<---------------cut here---------------start------------->8---
(defmacro defun-bug->url (name url &optional docstring)
  "Macro returning yankage #bug URL.

The `interactive' function that the macro returns is then referred by NAME.

Please provide a DOCSTRING."
  (let ((fun (intern (symbol-name name)))
        (doc (concat docstring "\n\n"
                           (format "Yankable result: `%sNUMBER'." url))))
    `(defun ,fun (number)
       ,doc
        (interactive
         (list
          (progn
            (when (not (boundp 'debbugs-gnu-bug-number))
              (setq debbugs-gnu-bug-number -2))
            (read-string
             (format "Bug number (%s): " debbugs-gnu-bug-number)
             nil nil debbugs-gnu-bug-number))))
      (let ((str (format "%s%s" ,url number)))
        (kill-new str)
        (when current-prefix-arg
          (browse-url str))
        (message (format "%s killed." str))))))

(defun-bug->url my/guix-issues "http://issues.guix.gnu.org/issue/";
          "Add URL of bug NUMBER to `kill-ring'.")
(defun-bug->url my/guix-debbugs "https://debbugs.gnu.org/cgi/bugreport.cgi?bug=";
          "Add (old) URL of bug NUMBER to `kill-ring'.")

(defun my/guix-data (package)
  "Add URL of PACKAGE to `kill-ring'.

Yankable result:
`https://data.guix.gnu.org/repository/1/branch/master/package/PACKAGE/output-history'.

With `universal-argument', load URL using `browse-url'."
  (interactive "sPackage: ")
  (let ((url
         (format
          
"https://data.guix.gnu.org/repository/1/branch/master/package/%s/output-history";
 package)))
    (kill-new url)
    (when current-prefix-arg
      (browse-url url))
    (message (format "%s killed." url))))
--8<---------------cut here---------------end--------------->8---


And because I find Message-ID and public-inbox nice interface, I also
have:

--8<---------------cut here---------------start------------->8---
  (defun my/public-inbox-insert (number)
    "TODO"
    (interactive "nBug number: ")
    (let* ((meta  (car (debbugs-get-status number)))
           (inbox (car (debbugs-get-attribute meta 'package))) ;Probably 
inaccurate for the general case
           (raw   (debbugs-get-attribute meta 'msgid))
           (msgid (replace-regexp-in-string "<\\|>" "" raw)))
      (message "Message-ID: %s from %s." msgid inbox)
      (my/piem-inject-thread-into-maildir msgid inbox)
      (notmuch-command-to-string "new" "--no-hooks")))
--8<---------------cut here---------------end--------------->8---

which can be adapted (by removing the part about emacs-piem, great
package BTW! and the part about emacs-notmuch).

Well, I have in my TODO list to implement the extraction of Message-ID
from Emacs-Debbugs.  But it is not about debbugs.el and instead about
Gnus.  It could be very helpful to have a way to stash to the kill-ring
the Message-ID of one specific message in the thread; and not only the
Message-ID of the first message in that thread.
