I'd suggest that using a scissor jack (or any jack?)
under a control arm *might* pose a risk
given movement of arm, and, would suggest that if used at front
lower arm, vehicle weight might deform the lower arm
mounting brackets.
I've seen tire jockeys use a floor jack at the rear trailing arms
but then they have two mount points.
Proper use of the stock jack allows one to more or less
keep their hands and arms away from vehicle underside.
