Excuse me for replying with out reading all 10 pages.
On traction:
The wieght of the tire and axle will provide limited traction, not normal traction. However with standard shackles this tire would be in the air free wheeling.

Revolvers are an improvement for traction.

On "unloading":
You say in theory its dangerous.
I say I did it and it did work without issues.
I will say it does handle different, like any suspension mod would do.
Lets go for a ride and you tell me when the revolvers "unload" and we are flung from the earth.
The above graph has a problem also, the straight drop would only happen if all the sudden the ground dissapeared.
The axle will not drop any faster than you drive up a hill/rock/stump/ramp.
The only way you will flip is if your center of gravity is high enough to flip you before the revolver begins to articulate. The only stability loss you get is the loss of the counter weight of one tire and half an axle. If the stability is that bad, I think its time to reconsider the line you are taking.

Revolvers are slightly more tipsy, but only because their range is greater. Over the same articulation range they are no different.

On damaged equipment:
Its not a drop in and you're done mod. There are limiter straps or diveline and shock mods needed.

If set up corectly revolvers will not damage your vehicle.
