Why high-end cable manufacturers don't post measurements?

Let me know when one can measure tonality and soundstage of a cable with an oscilloscope. I’ll wait. 

Miller, your use of that KenRockwell article for dramatic effect is totally disingenuous. 

Megapixels matter very much, but not if the sensors actual surface area is small. Which is why claiming you’ve squeezed 20+ MP onto a 1.7” sensor is meaningless, because it won’t be able to collect the same amount of light for any given shutter speed as a larger, smaller MP sensor.

To many words to say nothing!
Ok. 
" It depends on the system. Some systems will confound the most skilled listeners. Some systems are relatively immune to cable effects. Other combinations are like flipping a switch."

Which systems do sound different and which don't?
Why is that? What parameter of the system make the difference?
The truth is that you don't know.
I DO.

For the other guy, who claim that a cable length is a measurement, or it's gauge. Would you buy a car with that kind of information?

"For the other guy, who claim that a cable length is a measurement, or it’s gauge."

Huh, I do not like the idea of being "the other guy", but here I am. However you take it, length is a measurement and gauge should be, too. How pertinent are they is up to the individual user, but measurements they are. I would not mind knowing how long the car would be, if bought.

If I remember your identical although way more visited thread from some time ago, you consider gauge as the most important cable measurement. After using the formula based on DF, it all comes down that we need cables with gauge 0.

Why high-end cable manufacturers don't post measurements?

Sure they do....my cables are clearly marked on the manufacture's packaging.  My interconnect clearly state 1.0m and my speaker cables are 2.5m.  You gotta look closer.
