4. Struggle to come to a conclusion on what to do with the EOL OS because of internal political factors and the reality of how enterprise works.

This is the involuntary choice. If you cannot choose from the first three, you end up implicitly choosing the fourth.

I understand how it feels.

There is something you need to know about collective wisdom; the larger the org is, the lower it gets. Yes the application works on Alma 8 and 9, but the management says ‘no’.

Any large enterprise still running RHEL 5 in Prod (or even, yes, older RHEL versions) has fully accepted the risks

It is more like ‘involuntarily end up riding the risks of using unsupported old software’. RHEL 7 and RHEL 5 are in the right order.

RHEL sells an unrealistic expectation that you don’t need to worry about the OS for another 10 years, so the enterprise gets designed around it and becomes unable to handle an OS upgrade, ever.

I am not. I worked hard to make our application support RHEL 8 and then RHEL 9. And then the politics takes over and the big wigs start an extended bickering over who should pay for the OS upgrade… which never happens. Sometimes hardware partners don’t support the upgrades, which means OS upgrades also end up requiring new hardware.

I blame Redhat.

…hope…
