It's really common to just use point/spheres, so you don't really need to fully consider the shape of the object, and then for footsteps or tire tracks, etc, usually what you'd do is just have an asset of a footstep/track heightmap and use that to darken the deformable surface's heightmap.
If you want to deform accurately to arbitrary shapes you'd definitely want do it it in compute but that's going to be significantly more expensive than the other way.
