Are you looking for an editor that can format YAML out-of-the-box or with plugins? In my experience, most editors only support a small number of formats out of the box and extend that functionality with plugins. I have yet to find a solid, production editor without a decent YAML formatter. If you’re using one of the common commercial ones, Red Hat maintains many that work explicitly for Ansible.
This is just distributed functions, right? This has been a thing for years. AWS Lambda, Azure Functions, GCP Cloud Functions, and so on. Not everything that uses these is built on a distributed functions model but a fuck ton of enterprises have been doing this for years.
