I want to construct edit-menu dynamically depending on event.
Using the technique, code will look:

(define-key global-map [mouse-3]
  (lambda (event)
    (interactive "e")
    (let ((my-edit-map (my-edit-map event)))
      `(menu-item "Edit menu" my-edit-map
                  :filter ,(lambda (_) my-edit-map)))))
;; delete-selection now works correctly with yank invoked via the mouse-3 menu
(delete-selection-mode +1)

(defun my-edit-map (start-event)
  ; ...
  menu-bar-edit-menu)

CONCLUSION:
I appreciate your change and I think it is needed.
