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.
