I agree that most of these things don't belong in a data format.
But for metadata it would really make sense to be in there IMHO, and
information about the projection/CRS as well. Data without metadata is
worthless anyway (in an ideal world ...).
For shapefiles one can compare this to the .prj projection file and the .xml
