I think the answer is a solid maybe. I owned a 2018 JLUR that was horrible, very vague, wandered all over the road. After a new steering box, updated track bar, larger steering stabilizer, and an optimized alignment it was much improved but still no fun to drive at highway speeds in traffic. JL was a Feb 18 build so fairly early down the line. I replaced it with a JTLE that was a good improvement right out of the box, still wandered but better. Last fall I had the TSB completed that swapped the aluminum steering box for the 2021 standard steel box and a lot of the slop and wandering disappeared. It's still a little squirrely in traffic (wind off of other vehicles seems to move it around a little, similar to driving on windy days thanks to the flat sides.) I think they are on the right track, my main complaint is that the electric steering feels very overboosted which contributes to the wandering through overcorrection, and that should be tunable to speed and 4x4 mode. I've heard rumors of a recall since the JL days, nothing so far though.
