You're right, and fortunately we were saved from that pain because we
procrastinated so long. And we skipped v5 completely.

didn't cause you packed decimal problems with Truncation and the like. Or same

Lack of a "P" in the " ⁸ ⁹ A" column of the table indicates
instructions are not "privileged".

z/OS does not support setting the clock past the end of the first epoch. Some
forthcoming z/OS release will.
Until then it would probably not be a good idea to try to fake out the system.
Things will break.
z/OS does support expiration dates (such as mortgage end, etc) beyond the
first epoch.
On z-architecture, only machine instructions that change or set the TOD
clock are privileged. The STCK and STCKE instructions only provide
read-only access to the TOD clock and are not privileged or restricted
by hardware, but they are not taught in programming texts either.

In fact, I'm not certain that the clock is protected, but the user interfaces

What about vendor packages that are off maintenance, the vendor has gone out of
business, were licensed for a OTC and have been forgotten about, etc.? Any CBT
or similar packages?
