But I´m not sure, if Sigma implemented this function.

Oh, it's implemented; you only have to look at X3F files from supported cameras to see how.

2) The real advantage would be, that binned superpixels with square of the photodiodes area, are more sensitive

Alas with the noise characteristics of current X3 implementations, the improvement is small vs. simply downsizing the image; the most anyone has claimed after testing is about 1 stop for LOW vs. HI downsized.

I think that various RAW image sizes may not be result of really connected photodiodes before the capture, but after the light is captured by the normal pixel array.

Line and pixel skipping would produce significant aliasing artifacts.
