Looking at this, it got me to wondering--what is the reason they say not to operate it in lo range without the hubs locked in? I mean that should give you 2wd low, but what would it possibly cause damage to? Is it a later transfer case issue?
Component breakage, I presume. Axle shafts, u-joints could break from impact load. Running in 2WD permits low range on pavement, while 4LO is forbidden on pavement. Same reason Jeep does not mark the 2LO position on the D20/D300 CJ shifter. There is no detent, but it's easy to find the position of the handle at 2LO.

It's there, between N and 4L.

Blockchain the vote.
Tim is right, protecting the drivetrain components is the theory. I tend to disagree to some extent. Shift to 4 low and make a tight turn on a hard surface, even packed gravel there is enough bind through the tires all turning at different speeds to make the tires chirp and even the suspension to hop and kick as the tires lose and gain traction.
There are also times when 2 low is all you need for control and to reduce load on the drivetrain and brakes, example being the typical mount pass trail in Colorado. My truck spends a lot of time in low range, but a fairly low amount of time in 4 wheel drive.
To add more to the equation there is also the option with some transfer cases, d300, d20, np205 with a twin stick and modified pills or an atlas you can use front only in low range to aid in maneuverability. In front wheel drive with just a bit of tire slip and the wheel cut sharply it’s amazing what that does to making a tight turn, it will pivot around the inside rear tire. This is hard on parts, especially if you are driving through the brakes with just the front engaged. This explains it quite well and just uses a front wheel drive car to show it in practice https://m.youtube.com/watch?v=qhYt1f2qU7c
Try it it’s fun

So what I'm hearing is that in CO if I want 2 lo to keep my speeds down there's nothing wrong with putting it in 4 lo and having the hubs unlocked (or finding that magical J-pattern 2-lo spot for the D20).
I don't have the twin stick or anything...not really worth the money for what I'm doing. Looks like fun but I'm not doing anything to need it...lol

Your backside will thank you
Oh man after a 4 hour drive on Thursday I could only take like 2 hours or so on Friday on the drive home...finally wadded up my sweatshirt and sat on that so I had some support and that absolutely helped a ton.
I used 2wd low in my J10 all the time. Especially when it had the stock 2.73 gears. There were some driveways I literally could not drive up because the engine would stall (T176 4sp manual). So I would just drop the 208 into 4-Low, and then drive up the steep driveway with zero issues.
I was never going more then 5-10mph. But to my knowledge, the reason Jeep said "dont do this" is because it makes it pretty easy to break parts in the rear axle. With the hubs locked, the torque is split to all four tires. In 2wd low, only the rear gets it. And I know a guy that blew the spider gears in his scout driving in 2wd low. He lived in a steep road and would pull a trailer with fire wood. So he used 4-low for the extra pulling power. The D44 was unhappy with that decision after a while.

Makes sense, although I'm not doing it enough or going to be pushing it hard enough to really be worried about it.
Doing what you are doing it will be quite happy

Or the alternate ... for me after the QT part time kit from Milemaker was to lock up the hubs, but forget to activate the QT with the lock up switch which was the way the kit was supposed to be used, but it worked as well depending on the profile of the trail... until... the light bulb went off
