I would argue that it's more important than ever for effective engineering change management. With how easy it is have AI make changes to a system, I'm reminded of this tweet from DevOps Borat:

> To make error is human. To propagate error to all server in automatic way is #devops.

I'm not sure if YAML specifically is the best format, but we absolutely need something that offers a single readable source of truth for people to manage and reason about changes.
