I say no, but that's me.. It's not like you're going to run the DWS year round. If you have the awesome michelins for summer or 3-seasons, get winters for winter.
I've had the predecessor of the DWS on a Subaru and yes, it did ok to Whiteface trips in whiteout conditions. But the e39 rwd on snow tires felt better (we took two cars on one trip back in 2007). Neither were particularly high power cars either. But when they let go, the DWS or A/S will tend towards white knuckle as opposed to more progressive slip of the winter.
If you are worried about #2, wear, go for H or V rated winter tires, e.g. Dunlop winter sports, wear slowly or the blizzak LM series. And drive easy on dry. I've not had a problem with wear.
