But the question is how much support do you really need? It's all dependent on the saddle rails.
Have you ever wondered if there was more to life, other than being really, really, ridiculously good looking?

And can something support something, if there's nothing to support?

I'm not an engineer, but I can't really imagine where a force pushing the part of the saddle rails that's between the yokes down would come from.

Then again, I can't use a caliper either, so what do I know.

For what it's worth. I have a KCNC post on one of my other bikes, and I've had it for 4 years now, with a Ti railed saddle with no ill effects. I am quite confident it would be fine with a carbon railed saddle as well. Not really an issue honestly. I think over torquing the fasteners would be more of a problem then all 150lbs of me sitting on it. I used a carbon cradle developed similar to the KCNC cradle, and it had no ill effects on my carbon railed saddle. The carbon cradle failed eventually, but it had no effect on the carbon railed saddle.

I've seen carbon rails crack, and that was already on a Thomson. That being said, I'm not a big fan of the KCNC setup for carbon rails either.

In all fairness, unless you increase the length of rail being supported, it probably doesn't matter much.

Is someone still riding his carbon cradle?

A friend and very enthusiastic weenie "stole" mine and that's still going strong. I lost track of how many bikes are in his collection, so I don't know how many miles it's seen so far.
