My understanding, from discussions here a couple years ago, is
that several releases ago most such restrictions were removed
from catalog services, but remained in JCL and other archaic
APIs.
A subsequent release introduced a PARMLIB option to control
the facility in catalog services, making the default new-style
(few restrictions).
A yet subsequent release changed the default to be old-style
(restricted).
Apparently abhorrence of liberty is the modal attitude of z/OS
programmers.
