You are deluded if you think snow and ice traction are unaffected by
tire pressure. Make sure you note it in your next accident report, and
pay up on contributory negligence.

I didn't say it had no effect, I said it doesn't have much affect.
How much more flex do you think 35 psi provides? What exactly do you
think causes 35 psi to provide more traction? If you don't answer
you
will have shown that you don't know what you are talking about.

Tire footprint and optimization with suspension dynamics.

Footprint is correct. The rest is grasping at straws. Now how much
do you think the footprint changes when going from 35 to 45 psi? I
think we can agree that you would be hard pressed to tell the
difference by just looking at it. When you see a tire and think "soft
tire" it is usually in the low 20s if not lower.
Now let me ask you, do you run the latest sticky sport compound tires
on your car? No?! Why not? Could it be because they are expensive
and wear out quickly? IOW you are passing up the option of having
higher cornering limits and shorter braking distances to save a few
bucks. To quote you, "Make sure you note it in your next accident
report, and pay up on contributory negligence."
Many people run all season tires year round rather than switch back
and forth between summers and snows. They don't provide the traction
of snows, but they are willing to accept that compromise based on the
mix of driving conditions they expect to encounter. Inflating your
tires to the high side of the stock specs is no different. It is a
trade off we are allowed to make. And again, the effects are
minimal. I drove home on snow covered roads again today with no
problems.

Good luck. Suit yourself. The contact patch changes dramatically with
inflation pressure as well as suspension loading, camber, roll steer. I
would expect this to be particularly so for low rolling resistance tires.
Perhaps you should ask someone at Toyota what they think of your street
driving experimentation. Better yet, ask a product liability attorney.
Yes, I do run soft compounds on the sports car, and I have dialed in the
proper pressures for a variety of road surfaces and events. None of
them on the street.
Yes, I do use separate sets of high performance and winter snows for
each street vehicle. Properly inflated.
Better dial up that attorney.
