It's not a new range of XTR, it's a different range for a different style of riding.
Downhiller don't required says, a triple or double chainset, tend to have a narrower range of cassette (11-28), nor a clipless pedals (a personal preference), etc.
I doubt it would be a good idea for touring at all, overkill TBH when an XT or even Deore will work just as well.
