You do :P. if you look hard enough there are more than a few first hand accounts, as well as people alluding to what previous owners of their car experienced.
It's only only rolling diameter but grip tolerances between the front and rear. On non symmetrical full time and system, it's less of an issue.
Quattro and subarus awd are very different from each other.
There is no proven real world failure of wheel bearings from low offset wheels. I'm at 160k, and have run <et30 9"+ wheel set ups for over 80k. I am on my original wheel bearings. Thats right, they haven't needed to be changed once.
