Re: The question is

The question is - why do Nikon not make G type auto extension tubes based on TC14e, 17e and 20e?

While there would be no screwdriver AF drive for pre AF-s lenses, the internal diameter would be wider than Kenko - resulting in less wide aperture vignetting on FX using 300mm and longer primes.
The day Nikon announce them my order goes in.

Many problems turn out to be a lack of intimate knowledge of complex modern camera equipment.
