Again, your problem is that you keep referencing the angle between the tire and car's vertical; camber. That's not what matters. It's the tire's angle with the ground that is the important part. The difference is body roll. And the effect that makes up for body roll is camber gain. Therefore it's feasible to build/tune a system to keep the tire at a fixed angle with the ground at all rolls/compressions. Now the rest of the misperception is the assumption that you don't need more camber gain. And you can't say that without measurements. And yes I have them. But then you can get into a debate about increasing loads and proper camber angles, so it really don't progress the topic much.

Basically, at a ride height of -2", the stock length traction arm and RUCA length set to -2.25* camber will gain 1* of camber per 1" of compression. If you shorten the traction arm by 1/4", the camber will gain 1.5" per 1" of compression. All measurements done in my garage.
