Given that the front axle on an AWD vehicle is more similar to a FWD than RWD, the following probably applies:
from: http://en.intraxracing.nl/techniek/c...toe-intoe-out/
As such, with slight static toe-out you will likely run closer to 0 dynamic toe than you are with static 0 toe. Also you will reduce moving from toe-in under spring extension/decompression to toe out under spring compression that should benefit decreased bumpsteer and potentially tire wear?
Just some thoughts ....
Also there's a difference between static and dynamic toe. Especially on a frontwheel-driver you see this happening.
The same goes for a rearwheel-driver with independent suspension left and rear.
What happens is that when torque is applied ; The driven wheels pull themselves forward trying to toe-in.
Now it depents on the construction of the suspension how much the toe-in will increase.
On streetcars this effect is a lot bigger than on race cars as they use softer rubber bushings in the suspension-joints.

Pretty sure it toes in both front and rear with travel. That's why the rear bump steer correction bushing lengthens the toe arm.
If you want a car that spins though, make it toe out in the rear with travel.
As for the original post though, I've ran -2.5* and 1/32"-1/16" toe out for years on different cars and never really had any issue with shoulder wear. Could be some truth to it.
Anything more then 1/16" though made the car want to wander too much for my likings and made it nervous feeling in the rain.
