Could you put jack stands under the QuickJack's ramps?

When I first got them, I did have a minor bit of apprehension about the linkage that locks them in one of two lift heights, and further, I did contemplate the idea of additional security by placing traditional jackstands under the car while I'm actually under it.
But, to be honest, I've grown accustom to them and have been under the car many times. (They are rated for this kind of use)
With that said, here is how I specifically use my Quickjack. I raise it up with the hydraulic unit, lower it down against the mechanical lock, then just
slightly raise it back up with the hydraulics, without actually unloading the mechanical lock.
With this situation I essentially have created a situation where there has to be a complete failure of both the hydraulics AND the mechanical locks for the car to come down.
Possible? Yes. Likely? No.
Now if I was going to get under there and start yanking on things hard, I again might think about using some additional jackstands to ensure my grape doesn't get squished...
=====================
BTW, I did indirectly know a guy that was under his car with only a hydraulic jack. It came down on him and crushed his chest. He didn't die right away and his wife came out to find him. SHE DIDN'T KNOW HOW TO OPERATE THE HYDRAULIC JACK. He died later in the hospital.
My wife told me this years ago (her co-worker), we went out that moment and she learned how to use a jack. When I got the Quickjack, she learned how to use it too.
