You're confusing z/OS with Unix where all programmers are systems programmers
who can do anything they want. z/OS is NOT about be welcoming and encouraging.
It's about what's best for the business. Your on a multi-million dollar
computer shared by thousands. As a business programmer (not Unix sysprog),
you're not qualified nor authorized to make these decisions.
Programmers leave z/OS for Unix in order to be in full control. Why do you
think it's difficult to get z/OS programmers.

These statements cause me to pause. They seem somewhat antithetical to
welcoming and encouraging people to use the mainframe / z/OS.
Why is it absurd to allow everyone to do a Proof Of Concept on z/OS?
Is there anything about z/OS that would cause you to worry about the
security and stability of the system?
Do you not trust a tiny VM / LPAR running a test instance of z/OS with
absolutely minimal resources explicitly for such PoCs?
I'd think that it would be a huge win for the platform to try to get
more people to do things on it.
No, not all PoCs are vital to the business. But I think that it's
difficult to tell if any given PoC is vital until /after/ it has been
tested.
I suspect that there were people that thought that TCP/IP wasn't vital
to the system back in SNA's heyday. Yet here we are 20+ years later and
the idea of having any system without a TCP/IP stack is unthinkable.
How long would TCP/IP for the mainframe have been delayed if someone
didn't allow such a PoC until /after/ evidence showed that it was needed.
I sincerely doubt that operators /needed/ to create programs that
printed interesting things to printers after hours. But I suspect that
many learned a thing or two about the system while doing so.
I would sincerely hope that VM / LPAR could contain anything running in
a tiny z/OS instance such that it couldn't be disruptive to the system.
Or, if it was somehow disruptive to the system, that might be a good
indicator that something needs to be tuned or a bug needs to be fixed
thereby enhancing the larger mainframe z/OS / z/VM community.
I think that encouraging people to do things on the mainframe / z/OS is
a *GOOD* thing.
