To be fair I cannot trust your shape in your jsonrpc, I am not sure if id is truly an integer or if you sent me an integer by mistake, same as params or even the payload of the params' param, this is why we ended adopting openapi for describing http interactions and iirc jsonrpc specifically can also be described with it. At least in the schema part no one would say it is ambiguous, also one does not need do heavier parses, the obj is a tree, no more checking on scaping strings, no more issues with handcoded multiline strings, it is dropped the need to separate attributes with commas as we know the end tag delimits a space and so on.
