You dismiss, elsewhere in this thread, the need to be on the same OS and package versions for years. That’s what people want sometimes. They don’t want to tinker with the system. They don’t need any new functionality, not this year, not next year, not in five years. They built a service, it works, and they can deploy to RHEL and (mostly) forget about it for a long time. As the end of the LTS period approaches, they can do the work to migrate and then forget about it again for a decade. Note that “they” is not just the organization running the system, but also the vendors of bespoke or otherwise niche software used by the organization. Any problem might mean getting billed big bucks per hour of engineering work.
