> I'd like to see the RHEL stability model go away too and force people to complete their automation and solve the problems of being able to rebuilding on demand - and actually doing it.

In this model, what happens when the next Python2->Python3 breaking change comes along?

Using whatever Python your distribution needed is bad practice. Own your application environment, there are plenty of ways to do this, such as Nix and Docker, which make your Python environments reproducible across systems.

Also, Enterprise Linus is one of the reasons (definitely not the only) that the migration took such a long time. Too many enterprise shops that stuck with Python 2 because it's the lazy thing to do. The tech debt grows every year you don't move with the ecosystem.

How far down does "own your application environment" extend? How about libc? What is the role of the underlying OS?

>> How far down does "own your application environment" extend?

It depends on the needs of your application.

>> How about libc?

If you need to make sure the underlying libc has what you need, you must either bring your own libc or have sufficient feature test macros and adapters to account for possible differences.

>> What is the role of the underlying OS?

It depends on what the application requires. What operating system features, if any, do you require? Do you have any timing or scheduling requirements that are sensitive for your application? Do you need real-time responsiveness?

How does the operating system handle failure scenarios? What guarantees, if any, does it make when hardware fails? Is it okay for your application to crash if a portion of the computer's memory or disk borks?

Ideally none, with scratch containers for applications and the bare minimum running under your orchestrator which becomes your main interface.
