So the jackasses will have cost the company far more than the 20

gigabytes per volume is going to be other than totally inadequate in
the next ten years? Laptops now have 100 gigabytes and up on a single
drive. FBA will require major changes to spool management but we
might be able to get away from the one track IPL text. I can see
various FBA types such as: ones with file systems with all
directory/file name/member name information in Unicode, ones with just
z/FS or successor file systems and looking like true Unix volumes, and
ones that are structured to be only VSAM/PDSE related volumes. There
might be other variants once the bottleneck of CKD is broken. MVS
might even be able to recognize a DVD.

actually I used similar argument as part of the original justification ...
projecting enormous total life-cycle cost savings by moving to FBA ... in
addition to a whole variety of performance improvements that would come as part
of moving to FBA.
lots of past posts mentioning the whole FBA, CKD, etc period
