I think one could write something like a modal scrolling,
like in this pseudo elisp.

(defun scroll-modal-pre-command-hook ()
   "Pseudocode!"
   (when (eq this-command 'scroll-bar-command)
     (save-window-excursion
       (while (scroll-bar-command-p)
         (apply 'scroll-command)
         (read-event)))))


I don't know if that's what eveybody has in mind here.
