I'm not sure in what way you think most modern routings are weak, but I think they're weak because clients don't demand otherwise.
In the old days architects worked for groups of golfers who were going to walk the course, and wouldn't put up with long hikes to get to the next elevated tee. Today, the clients are developers who don't particularly care about walkability, and whose "other amenities" sometimes trump the best location for golf holes. Honestly, in my first ten years of practice, I had more clients express interest in spreading out the holes (to increase cart revenue), than in getting greens and tees close together. It hasn't happened lately, but I think that's because I'm talking to a client pool who knows me better, not because the business has really changed.
