I thought ground physics are more related to how the plane handles at the ground level like the nosewheel for example

I think msfs 2024 does have the potentail to have great ground physics.
The things shown in your video seems to me more like effects and interaction with other objects like engine heat blowing out while the wind is coming from the right side and the snow is blowing away ( and because of the engine heat it would melt) but i think you rather would want to see it gets blown of to the left side i guess.
and for this i think yes it might get better but that takes a bit of time to get there

You can also open the model folder from the airplane you would like to fly, and select model.cfg
Open it and put ; in front of the last to lines this will prevent loading the exterior and interior xml files.
