That doesn't seem to be hard to implement:

#+begin_src emacs-lisp
(add-hook
 'org-capture-mode-hook
 (defun my-org-capture-mode-hook-fun ()
   (add-hook 'kill-buffer-hook
             (defun my-org-capture-inhibit-accidental-kill ()
               (user-error "Please don't just kill org capture buffers"))
             nil 'local)
   (add-hook 'kill-emacs-hook
             (defun my-org-capture-barf-for-left-capture-buffers ()
               (dolist (b (buffer-list))
                 (when (with-current-buffer b
                         (bound-and-true-p org-capture-mode))
                   (user-error "Please care about org capture buffer %s"
                               (buffer-name b))))))))

(add-hook 'org-capture-prepare-finalize-hook
          (defun my-org-capture-prepare-finalize-hook-fun ()
            (remove-hook 'kill-buffer-hook
                         'my-org-capture-inhibit-accidental-kill
                         'local)))
#+end_src

Would you consider to do something like this by default?

BTW, what about my question whether my original bug report can be
closed?

TIA,

Michael.
