Precisely!
I didn't even know this type hub existed until I was swapping the cassette off this freehub and noticed the "weird" threaded end.
I did order the replacement cassette, just kept it at the same 13-26 for this bike.
I like having the smaller gear on my climbing bikes for when I descend. Always trying to up my top speed and sometimes it helps to be able to spin out at a high speed to carry momentum as you tuck and go aero. But yeah, day to day riding I have no need.
