But note it's what I want, maybe this hack comes in your way in
situations where you like the original behavior more.

Anyway, here's the hack:

--8<---------------cut here---------------start------------->8---
(defun my-yank-reset-yank-pointer ()
  (unless (eq last-command #'yank)
    (setq kill-ring-yank-pointer kill-ring)))

(defun my-yank--before-ad (&rest _args)
  "Before advice function for `yank'.
1. avoid persistent change of kill-ring-yank-pointer after
`yank-pop', and before next kill.
2. For yank-pop, move the really yanked text at the beg of the
kill ring."
  (unless (eq kill-ring kill-ring-yank-pointer)
    (let ((last-yank (car kill-ring-yank-pointer)))
      (when last-yank
        (setq kill-ring (cons last-yank (delete last-yank kill-ring)))
        (my-yank-reset-yank-pointer)))))
  
(advice-add 'yank :before #'my-yank--before-ad)

(defun my-yank-pop ()
  (interactive)
  (if (eq last-command 'yank)
      (call-interactively #'yank-pop)
    (rotate-yank-pointer 1)
    (yank)))

(global-set-key [(meta ?y)] #'my-yank-pop)
--8<---------------cut here---------------end--------------->8---
