Why use unstable_httpBatchStreamLink in React server components?

When using create-t3-app I noticed that they were using unstable_httpBatchStreamLink in their TRPCProxyClient when using RSC. I find this strange, since you already have access to the actual appRouter, doing an HTTP request to your own server adds a lot of overhead. Why use TRPCProxyClient with unstable_httpBatchStreamLink and why not just use createCaller? I understand why it's done when rendering 'use client' components on the server, because you don't want server code bundled into the client code. But I fail to understand why they opted to also use this method when rendering server components.

Best to ask on that project, but they probably aren't wanting to host tRPC within the NextJS backend Whether that's due to a misconception or a better understanding than you have, is best to find out from their github 🙂
