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.
