How many flawless, painless major version upgrades have you had with literally any flavor of k8s? Because in my experience, that’s always a science experiment that results in such pain people end up just sticking at their original deployed version while praying they don’t hit any critical bugs or security vulnerabilities.

I’ve run Kubernetes since 2018 and I can count on one hand the times there were major issues with an upgrade. Have sensible change management and read the release notes for breaking changes. The amount of breaking changes has also gone way down in recent years.

I applaud you for having a specific complaint. 'You might not need it' 'its complex' and 'for some reason it bothers me' are all these vibes based winges that are so abundant. But with nothing specific, nothing contestable.
