Exposing server-side caller and tRPC caller/helper through the same export?

// server.ts
import "server-only";
// ...
const caller = createCaller(createContext);

export const getQueryClient = cache(createQueryClient);

const helpers = createTRPCOptionsProxy({
  ctx: createContext,
  router: appRouter,
  queryClient: getQueryClient,
});

export const api = {
  caller,
  helpers,
};
