Can the strategy to store information from previous render be used in a custom hook?

I was reading the strategy in the new beta docs, and was thinking whether it could be used in a custom hook? I tried doing it and it worked, but wanted to know whether it's advised or not.

To explain in code, my question is whether this is OK (same example from React docs but trend logic moved to another hook):

import { useState } from 'react';

const useCountTrend = (count) => {
  const [prevCount, setPrevCount] = useState(count);
  const [trend, setTrend] = useState(null);

  if (prevCount !== count) {
    setPrevCount(count);
    setTrend(count > prevCount ? 'increasing' : 'decreasing');
  }

  return trend;
}

function CountLabel({ count }) {
  const trend = useCountTrend(count);

  return (
    <>
      <h1>{count}</h1>
      {trend && <p>The count is {trend}</p>}
    </>
  );
}

function App() {
  const [count, setCount] = useState(0);
  return (
    <>
      <button onClick={() => setCount(count + 1)}>
        Increment
      </button>
      <button onClick={() => setCount(count - 1)}>
        Decrement
      </button>
      <CountLabel count={count} />
    </>
  );
}

以前のレンダーの情報を保存することについて説明している、リンク先の React ベータ版ドキュメントのセクションから始め、この issue にある custom-hook の例を確認します。このパターンが custom hooks に推奨されるかどうか、またその指針をドキュメントのどこに置くべきかを判断します。例によって裏付けられた明確な回答がドキュメントに示されれば完了です。
