Scrolling commands can be handled by this hook:

(add-hook 'window-scroll-functions #'pulse-line)

>                   other-window
>                   windmove-do-window-select

(add-hook 'window-configuration-change-hook #'pulse-line)

>                   kill-current-buffer
>                   delete-window))

(add-hook 'window-state-change-functions #'pulse-line)

A new command could ignore its arguments:

  (defun pulse-line (&rest _)
    (interactive)
    (pulse-momentary-highlight-one-line (point)))
