I do not think "JSON does not support incremental parsing, HTTP does" is the reason why JSON-RPC is less popular. Most typed languages give you two options for parsing JSON: - 1. General JSON values (hash maps of JSON scalar values). - 2. Strongly typed - convert JSON string to a specific type that you defined in your application code. You could use 1 to then use in a switch statement to branch to 2. You may have to parse the JSON twice in some languages to do this, but JSON is typically small and fast to parse.
