My take ....
If you want a road bike, buy a road bike. If you want an off roader, buy an off roader.
That said, I did some mild green laning on the previous model (XTZ660) and it was ok at it.
The only reason I see is if someone wants to travel and explore over long distances, involving dirt.
As a tool. I don't know how much joy the bike can offer on dirt and definitely not on the road.
