IIRC the extreme head nod often seen today is an artifact of show breeding. Here is a video of Strolling Jim, the first WGC Walker. He nods, but it’s in time with his movement and is a result of that movement. It’s not, IMO, “over the top.”

Listen to the narrative and where he came from.
My regular Marchador mare has a small head nod when she is in gait. Her movement, a marcha batida, is very centered and square and reminiscent of the type of movement Strolling Jim displays. That’s one reason I like her! The movement means if I’m going to ride her in contact I’ve got to have a very “kind” and steady hand otherwise I’ll beat the mouth up. It also means I have to be careful with bit selection for the same reason.
With ANY horse you have to ride for the task at hand. If the task is winning a blue ribbon in flat class in a show ring then you will ride to meet the standards of the class as interpreted and applied by the judge. That often means not just contact but significant contact. Many Walkers and Marchadors move in a more flashy manner when ridden with that type of contact. If the task is covering 20 miles on the trail then you don’t want to use “show ring equitation.” You’ll want to have the horse moving correctly, i.e., carrying himself, as that is a more energy efficient movement than just “lazing” along. And the rider can’t just slump in the saddle like an old sack of wheat. That pretty much guarantees a sore back (for both). And there’s things in the middle. If you’re going compete in Working Equitation you’ll be using at least three hand/seat techniques in a single run.
The TWHBEA does not have a formal Breed Standard. It never has. That is likely because of how the TWH, as a breed, developed. The closest thing are the judging standards of the old NHSC. Having been away from Walkers for a while I’m not sure who writes the standards for the Celebration or the Walker show circuit. They are important because what wins is what gets bred.
Select a horse based upon the job you want it to do. Walkers are good generalist horses as rule but within the Walker breed there are several different lines and each does one or more tasks better than some others. It’s possible to fit a square peg into a round hole but that will hard on the peg, the hole, and the hammer used to accomplish the task.
