Here are my observation of bicycle wheel slippage and fall modes, on
gravel and sand

It seems that FWD makes slippage worse / harder to recover.
Would Tadpole 2WD help? Maybe with tilting locked?

I doubt whether a tilting mechanism is a disadvantage if you compare
it with a 2 wheeled Python. I had the front wheel slip on both the
Python and the tilting trike. Not sure which one would slip and fall
first, but when I did fall both events went differently. The Python
slid away from me, I put one feet on the ground but the bike fell.
It hit the pedal and handle bar, then the seat. I myself went foot
first, then onto my bottom. I wasn't hurt (only a few scratches) and
the good thing was that the bike seems to go away from the rider
(like with my recumbent), which is much safer than a conventional
bicycle (entanglement). On the trike; the front wheel slipped and I
put one foot on the ground so the bike didn't fell over. Since this
was a test, I knew it was comming and was one step ahead. Otherwise,
I think you are more likely to hit bike parts (tires) when you fall
than with a Python.
My experience with cycling through the snow is like this: fresh or
wet snow is ok for most bikes, although not really for a recumbent.
Snow that is there for a few days and has been driven over makes
things quite a bit harder. A mountainbike with soft open tires might
still do. When things get really nasty I always prefer the classic
citybike, since there is less pressure on the frontwheel compared to
a mountainbike and it is easier to put a feet on the ground to stay
in control and slip through corners ;-)
