Sure, good points, makes sense.
Something else occurred to me. I used to drive BMWs a lot, 5 Series with rear-wheel drive. They were terrible in the snow. Once, I got stuck in a flat car park with my 5 Series.
Then I had two Maserati Granturismos, also with rear-wheel drive. Everyone warned me that these cars were a nightmare in winter. I can report that the Masi was far better than the 5 Series. Then I looked at the weight distribution, and everything became clear. The 5 Series had rear-wheel drive, with most of the weight on the front axle, while the Masi had rear-wheel drive with a very balanced, almost 50/50 distribution and thus significantly more weight on the rear axle. From this perspective, rear-wheel drive is not just rear-wheel drive; there are differences.
