This is usually an indication of a problem

This is confirmed by all documentation. What a "normal" user wonders
about is why B/W images become full CMYK colour images instead of CMYK
with CMY being "empty". When I check my images they are truly
  Type: GrayscaleMatte
  Endianess: Undefined
  Colorspace: Gray
  Depth: 8-bit
  Channel depth:
    Gray: 8-bit
    Alpha: 8-bit

OK. I will give this a try (and I hope you understand it right :)
