I ALWAYS use pinch welds on my 2-post. Two potentially notable differences are 1) the lift pad is longer than most scissor jack pads and 2) there is a rubber cover which provides a bit of cushion
I've never seen pinch weld damage from doing so. Escapes, Nissans, Kias, Toyota cars, tons of Subarus.
The exception was KL Cherokees where the lift point is buried UP in plastic cladding (dumbest design EVAR), where I machined custom adapters.
Also a '64 Falcon made me nervous and I used my adapters there
The way I see it, if the manufacturer says a given location can withstand ~25% (many variables, I know) of the vehicle's weight on the roadside, no reason four points can't withstand 100% of the vehicle's weight on the lift.
I have yet to observe damage. I've seen Subarus damaged where they clearly high-centered and came down on the pinch weld.
