When I said generated, I meant from the actual source code. I'm basically suggesting a literate programming approach with specification as code.

Like if @inertia made changes to the json-rpc, then specification changes would be accepted in the same PR. In the next CI build, documentation could be generated, but that's not what's important. What's important is that now the specification itself is deployed with the software and can be used to generate/verify a client.

From a single change, you have now affected several facets.
