I would not let the wheels stop me from doing an occasional backpacking trip, providing you are not on the far end of the heavy scale as mentioned above.
If, for example, you weight 170 and take 30lb's of gear it would be like a rider 200lb on the bike - not unreasonable (yes there is a slight difference between static and dynamic weight but not that much).
Also, the bike has front suspension to lessen the impact stress somewhat and one would assume you'd not ride as aggressively with a backpacking load as you would racing XC.
Just be sensible about the weight and getting airborne.
One problem with the internet is that it gathers all information together and can easily highlight optimal equipment solutions. In the "good ol days" people often didn't know better and simply set off touring with what they had. Imagine pre 70-80's when folks were using stainless steel rims and caliper brakes and still criss-crossing the country or world. Now it is easy to succumb to decision paralysis because all our gear is not top tier.
