Re: Why the hate?
There are validation schemas with JSON. If you want to see how far it can go, check out OpenAPI. I've not tried to track down validation schema for YAML, but in principle, I see no difficulty in doing so. I will note that because everything in a YAML document has a tag, a YAML validation schema could be done on a by-tag basis. I therefore suspect that could could get an adequate validation schema for YAML entirely in JSON.
