Is it possible to batch updates in multiple useSwr calls with unstable_batchedUpdates?

I have a batched API, all the useSwr calls on the same tick are sent to the server in one request. When the request completes, it looks like useSwr calls setState multiple times without unstable_batchedUpdates, so it causes multiple rerenders. Would it be possible to only rerender once when multiple fetchers complete at the same time?

You can have one fetcher with multiple API calls.

const { data } = useSWR(() => 'some-unique-key', () => Promise.all([fetch1, fetch2, fetch3]));

But this seems like a bad Rest API design. You should be able to fetch one endpoint and get a compound document with all three resources.

It's not a REST API, it looks a bit like:

const queuedKeys = {};
let timer;
useSWR('key', key => {
  if (!timer) {
    timer = setTimeout(handleQueuedKeys, 0);
  }
  return new Promise(succ => {
    queuedKeys[key] = succ;
  });
});

handleQueuedKeys would batch the APIs and send them to the server. When the request completes, multiple promises resolve and useSWR calls setState multiple times. I want to batch these setStates.

I don’t think this is possible. How can multiple custom hooks batch their internal setState?
