I would love it, but please don't add JSON-RPC to the world... It's too heavy for editor.

Anyone else noticing an uptick in confidently stated nonsense on HN? To write that JSON-RPC is "too heavy for editor", you have to not only misunderstand the cost of JSON encoding (trivial) but also the frequency of editor-tool interaction (seldom) and volume of data transferred (negligible). In addition, you have to look at LSP, MCP, and other JSON-y protocols and say "yep. There's where the UI latency is. Got it.". (Nope)

Are people who assert that JSON-RPC is "heavy" writing code we all rely on?

Harsh. But fair. JSON-RPC is one of the leanest protocols out there.

Is there a better option?
