But this assumes an "engineered" solution for each and every
vehicle.
If your vehicle had a solid engine cradle or other substantial
crossmember you can already raise the entire front end at once with
an
hydraulic trolley type floor jack,

I've heard that you can lift the rear of a pickup with a jack centered
under the differential. I never risked trying it.

No risk. I've done it many hundreds of times to move vehicles out of
the way in the shop. Just stay clear of the oil pan on the back or
you'll warp it. The nut (diff) is a stable jack point, though.
