Actually, the issue of losing true position under torquing of the lead
screw is almost certainly irrelevant to the hobby machinist.

It would take a lot of torque to generate any significant positional
error, and this under the acceleration of a rapid move, or rapid
deceleration. Absolute accuracy here isn't important. When acceleration
levels off, or the lead screw comes to a stop, the screw will return to
it's static form.
I doubt anyone here is contouring at 200"/min and trying to hold tenths
at the same time.
If someone wants to experiment out of curiosity, fine, but I really
doubt many of us here have hardware good enough (let alone inspection
equipment) to quantify any benefits.
