FWIW (not an argument against) -

You can go to buffer *Completions* and hit `C-h b'.

Or you can use this (which I proposed that we add to Emacs):

(defun describe-keymap (keymap)
  "Describe bindings in KEYMAP, a variable whose value is a keymap.
Completion is available for the keymap name."
   (list (intern
           "Keymap: " obarray
           (lambda (m) (and (boundp m) (keymapp (symbol-value m))))
           t nil 'variable-name-history))))
  (unless (and (symbolp keymap) (boundp keymap) (keymapp (symbol-value
    (error "`%S' is not a keymapp" keymap))
  (let ((name (symbol-name keymap)))
    (help-setup-xref (list #'describe-keymap keymap)
    (with-output-to-temp-buffer "*Help*"
      (princ name) (terpri)
      (princ (make-string (length name) ?-)) (terpri) (terpri)
      (princ (documentation-property keymap 'variable-documentation))
(terpri) (terpri)
      (princ (substitute-command-keys (concat "\\{" name "}"))))))

I bind that to `C-h M-k'. Then `C-h M-k co TAB RET' gives you a
user-friendly listing of `completion-list-mode-map'.
