How do you cache tRPC server responses w/Next App Router?

What is the correct way to define the cache for tRPC endpoints with [email protected] & Next App Router? Cache-Control headers are overwritten by NextJs (https://nextjs.org/docs/app/api-reference/next-config-js/headers#cache-control) Meaning the tRPC docs are not relevant (https://trpc.io/docs/server/caching) I have validated this with a very simple trpc route returning new Date().toJSON(). Current setup in create-t3-app appears to be 'no-cache' for these endpoints. NextJs will not respect cache-control headers set via responseMeta in the fetchRequestHandler, or via context.
