Was in CA and went to one day of the Senior Open.
Would agree that Kyle redid the course in Maxwell fashion. Not my favorite style, but he pulled it off well. Seems like he did a lot of re-routing from the aerial photos and the one visit I made to the course when designing in nearby Davis about 15 years ago.
I liked the contouring of the greens a lot.
Also saw many fw where he had drainage swales to one side. The main hazard wasn't the bunkers, but rather, if you hit the fw, you had a mostly level lie, but if you drifted off to the rough, you probably had a 10-15% side slope - not unplayable, but not as easy as the fw for both grass height and slope, both making the shot more difficult.
