This "one size fits all" approch does fit everywhere.  There are a
number of users (including _big_ commercial ones, with _large_ numebrs
of systems in the field) that have simple requirements like:

- how can I find out if the image I just loaded to RAM in OK (OK
  maning some checksum is correct, or some crypto-key could be
  verified, or ...) ?

- how can I find out which version of image is installed on this
  device in the flash?  Can I print something like an ID string, or a
  build timestamp, etc?

etc. etc.

zImage may work well in many cases, but there are also many cases
where in image format that allows for additional meta-data is
mandatory.

Best regards,

Wolfgang Denk
