Except the scenarios most reasonable people consider mixing tires is more like 4 at 20% vs 2 at 20% and 2 at 50%.
I'd take the mix of 2x 50% over 4 at 20%.
Like a bike, my understanding of the situation is that good tires in the back keeps the vehicle straighter in most scenarios. You'd lose in acceleration and ability to do better evasive maneuvers, but the vehicle is going to be more likely to stay controllably at a stand still. Putting good tires on the spinning wheels (ie: FF vehicle) is slightly different in the sense that you can do better evasive maneuvers, but stability suffers.
The average person is probably unlikely to constantly do all the effective evasive maneuvers, so it's recommended that you don't do it that way. But this is the "average" here. You have idiots with winters that crash and morons with bad all seasons that somehow avoid collision, even though they annoy everyone around them for their entire drive. There's too many factors at play.
If someone is an idiot or non-confident driver, objectively, it's recommended to stay home when the roads are like this. But what constitutes an idiot or non-confident (shouldn't have confidence) driver is a bit subjective.
