So apparently, design and compound can cater for a lot.
Unfortunately, snow performance on my front drive car is worse than my XC90 has in AWD mode with summer tires. (
Design and compound matters a lot, but it's still a tradeoff.
The easiest way to increase rolling resistance is to reduce the tread depth. Less deformation of the rubber leads to less rolling resistance.
So to improve rolling resistance, the designers can reduce tread depth and move to a harder compound, which trades off grip.
Modern tires are good, but everything is tradeoffs.
