They DO make cassettes with smaller range. Just hadn’t heard of them before, and didn’t see them on the website, because the are called a different model than the wide range ones.
They make 9-34, 9-39 and 9-42 in 11 speed, Xd freewheel., called the XCX plus cassettes.
Anyone running a Park/DH wheel or bike, this can be a very interesting option: light weight(less unsprung mass is great) and 10% smaller COGGS means you can run 10% smaller chainring for more ground clearance. Especially if you are running a 27.5 wheel, with its lower gear inches, your chainring can start to get awful close to the rocks on the modern low BB bikes.
It’s especially nice if, like me you swap a different wheel and tire into your trail/enduro bike for the park. In one quick and easy wheel swap you get a taller gearing with a grippier, tougher, tire for the park, and back to a lighter faster rolling tire and lower/wider gearing for the trail rides.
