Data type in Suspense mode with Conditional Fetching is different from document

[k35o]

Document states that when isReady is false, data is undefined.So if key will be Falsy, then data type should be guessed as Data | undefined.

function Profile () {
  const { data } = useSWR(isReady ? '/api/user' : null, fetcher, { suspense: true })

  // `data` will be `undefined` if `isReady` is false
  // ...
}

However, in version 2.0.1, it is presumed to be Data. And when key is Falsy, an error occurs.
Which behavior do you plan to proceed as positive in SWR?
