I don't foresee a huge issue. The lacerations, imo, would only be caused by extreme amounts of heating/cooling cycles during the few truly arctic weeks of winter, probably coupled with dry air, ozone, etc....they look tortured, not made of glass, imo.
Based on all this info...I'll store it somewhere dry (ie, not outdoors), and inflate them to max pressure. Roll the car 1/8 wheel-turn every month until the snow melts.
My only concern was cold weather storage when the tire is on the vehicle, not off like this bulletin describes. It's still a little cloudy in regards to that subject.
I'm going to do the same thing as you, inflate them to max, and not worry about it. I may even invest in these
I don't think this is going to be an issue, but I'm sure it would be a good idea for everyone to visually inspect their tires after a winter storage just in case.
