Alas, this chaos resurfaces with RECEIVE FROMNETWORK/FROMNTS/ORDER.
Many vendors haven't the administrative leverage to support FROMNETWORK
even though IBM supplies the GIMZIP tool.  z/OS is a fringe LoB to my
employer who requires as a standard that every product and patch be
supplied as a .zip file containing the payload plus a README.* containing
installation instructions.  I understand that IBM supplies products on optical
media for customers unable to RECEIVE ORDER.

IBM supplies no instructions, much less a tool, for packaging for RECEIVE
ORDER, and the antiquated Packaging guide fails to describe the optical
media format in the detail in which it describes packaging for tape reels.

The downsides of this are:

o PTFs are enormous.  At a recent release boundary, we switched to finer
  granularity packaging and our PTFs shrank by a factor of 10.

o Dependency entanglements are aggravated.  A customer may not be able
  to apply an APAR for a hot problem without bringing in all very recent
  unrelated service which that customer was waiting for his peers to field-test.
  (I think the term is "aging"  PTFs before installation.)
