I've sometimes seen books reference Kaiser Friedrich III as somehow bringing into the German Empire a culture of liberalism on the Western European model as a road not traveled by said Empire. But in looking both at Germany and the Kaiser I'm not entirely sure he would. There are plenty of rulers at the time who promise meaningful reform but when it comes to actually giving up any power they had balked and refused to do it. In particular Alexander II is the big example of this, though the Bourbon Restoration and July Monarchy are other examples of it at the other end. Would Kaiser Friedrich III, if he lived long enough, be a genuine reformer or would he be the Alexander II kind of all hat, no cattle?
