TRT, IMO, is to make `generate-new-buffer-name' mode-specific.
E.g., have a buffer-local variable 'uniquify-buffer-name' or a similar
property of the major-mode name, which would hold a mode-specific
function which is to be run in the buffer being renamed.

E.g., for occur-mode:

(defun occur-mode-uniquify ()
  (concat "*Occur: " (mapconcat #'buffer-name
                                (car (cddr occur-revert-arguments)) "/")
          "*"))

for help-mode:

(defun help-mode-uniquify ()
  (concat "*Help: "
          (case (car help-xref-stack-item)
            ((describe-function describe-variable)
             (symbol-name (cadr help-xref-stack-item)))
            ((describe-bindings)
             (concat "keybindings in buffer "
                     (buffer-name (window-buffer
                                   (car help-return-method)))))
            (t "???"))
          "*"))

etc.

Then `rename-buffer', `clone-buffer' &c will DTRT automatically.
