There is nothing simple about yaml. Only things that seem simple from a first glance.

Isn't this just a matter of, "Recognize when you're using config for something dynamic and refactor because config is no longer the best tool for that job"? And you can continue using yaml (or whatever config format you're using) wherever config remains the right tool for the job.

Someone already mentioned Ansible. I find it particularly terrible. And bunch of other half-assed DSLs, terrible templating languages and such.

I'm currently stuck in stage 4.
