I'm reminded of https://medium.freecodecamp.com/you-might-not-need-react-rou... which discusses how to write your own such functionality from scratch. I often find that before adopting third party code you really have to consider it and perhaps even leave it out and feel the pain before accepting that it's necessary and adopting it. And even once you do, you should be open to maintaining or replacing it. There's a cost to roll-your-own though, you might need to write additional documentation. For routing though, it's usually one function and easy enough to grok on its own.
