Hi,

I was mainly curious without any exact need at the moment. I just noticed that 
gdal2xyz.py can create xyz files with more bands than just one for z but I also 
had a feeling that GDAL cannot read such files directly back, which appeared to 
be true.

Generally speaking there might be some use cases for a multiband plain text 
format. I am remembering that some user on the Geoserver users mailing list a 
few months ago was after such a format. Use case was to query pixel values from 
a WCS service. Requesting a single pixel GeoTIFF makes things unnecessary 
difficult for such simple need.

Jukka,
  I'm not sure I understand exactly what you want but I have this old script 
which might help.

This is old enough it might need some minor updates for Python 3.

Not directly.
You could add a header line with the appropriate column names, by making the Z
column to point to a different column each time.
