I've gone a bit backwards and forwards on this - I'm a big user of crags packs and think they are great. But I reckon a chunk of the not insignificant price for the Atrack is its waterproofness. If you used it just as a crag pack I reckon you could potentially end up damaging the material enough to stop it being waterproof. It doesn't seem fragile (beyond the fault they fixed on the review pack) but if you are paying 200 quid for a pack that it waterproof mainly using it to drag along the base of cliffs seems a bit silly.
I'm still regularly using the Arcteryx Miura from this review https://www.ukclimbing.com/gear/rucksacks/medium/crag_packs_for_trad_climbe... it is still going great, no holes no problems more than a decade later. I don't think Arcteryx is doing anything comparable now, but there are plenty of crag packy things from various brands that look like they might last equally well and still are nearly half the price of the Atrack.
It is a very clever design but I still feel if you aren't relying on it to keep your stuff dry even in total immersion situations, it is a rather expensive rucksack!
