Restoration technology is constantly changing, and so Weidenhofer holds, "There's nothing that won't change over time. The renovations we are doing now won't last forever, and our followers will perhaps criticize us for doing such a poor job of it!"
維修技術不斷推陳出新，因此韋登霍夫認為「沒有什麼是永久不變的，我們現在做的維修也不會永久保存，後人來修時也許還會批評怎麼修得那麼差！」
