ISTR that either IBM continued to distribute the older IEBCOPY which
(sometimes) required authorization, or that some installations kept
such a restricted outdated copy available. Why? Auditor phobia?

This had nothing to do with auditing. It was just the native caution of
the DFSMS developers. IEBCOPY is *so* fundamental a utility they wanted
to make sure people had a copy of the old one...just in case something
happened that made it necessary.
And...something did. The zPDT systems of the day did not support the
necesary subset of the ECKD command set, exposing a bug that could be
circumvented by using the old one until the fix was available. We never
found this in testing because (suprise!) no real disk devices are
available that do *not* support ECKD as far as I know, and those from
IBM have not been available for 20 years or more.
