That's pretty much it. I think the main issue nowadays is that companies think full stack engineering means OG(FE BE DB) + CICD + Infra + security compliance + SRE.

If a team of 5-10 SWEs have to do all of that while only graded on feature releases, k8s would massively suck.

I also agree that experienced platform/infra engineers tend to whine less about k8s.
