In my experience it's the custom scripts in an attempt to separate infra from developers.
If you are using one of the major cloud providers and instead of just using a native IaC scripts, you have decided that it would be better if the developers only had access to your custom kubernetes operators to manage their infrastructure then you are the problem.
If you are using a deployment pipeline that developers have zero involvement in, and they just "import your Jenkins scripts" then you are the problem.
If you are using major cloud provider and rather than just using their managed kubernetes, you have decided to deploy your own, then the chances are that you are the problem.
Rarely have these approaches ever been stable, in my 20+ year experience they have never been stable. And they are the reason that "real DevOps" came along because developers could do a better job with less downtime if people actually engaged them.
