Since the server should be stateless and its an request -> reply flow it would be reasonable that the server supported both JSON-RPC 1.0 and 2.0? Just ignore the "jsonrpc": "2.0" and maybe another schema validation (no support for batch, no support for object params). The server would need to track if it was a 1.0 or 2.0 request because the response will depend on that.
