Building a dry-run mode for the OpenTelemetry Collector

That's very cool, thanks for sharing it with us

IMHO a no kidding JSON Schema would help that yaml-edit-and-pray a lot. I hear detractors saying "but it's so dynamic!!1" and yet opentofu, with a similarly dynamic input, mapping, and output problem space still has a schema introspection command

Or (bite my own tongue, I guess): an actual programming language like starlark or even a home-grown one the way vector does it
